Without this patch jumbo's will work but performance will be awkward since the TX size is not adequate for two whole frames.

This patch flips around the dependancy logic so that it cannot be selected unless BESTCOMM_FEC is selected first. Kconfig stops complaining this way. Also, the driver only works for arch/powerpc (not arch/ppc) anyway so it should depend on PPC_MERGE also.

From looking at other drivers, it appears that one should only call netif_rx_complete() when work_done < budget. To fix it, I changed the test in myri10ge_poll() so that it refers to to work_done rather than looking at the rx ring status. If work_done is < budget, then that implies we have no more packets to process. Any races will be resolved by the NIC when the write to irq_claim is made. In myri10ge_clean_rx_done(), if we ever exceeded our budget, it would report a work_done one larger than was acutally done. This is because the increment was done in the conditional, so work_done would be incremented regardless of whether or not the test passed or failed. This would lead to the WARN_ON_ONCE(work > weight); warning in net_rx_action triggering. I've moved the increment of work_done inside the loop. Note that this would only be a problem when we had exceeded our budget.

A reasonably common problem with some devices is that they will disable MSI generation when the INTX_DISABLE bit is set in the PCI_COMMAND register. Quirk this explicitly, guarding the pci_intx() calls in msi.c with this quirk indication. The first entries for this quirk are for 5714 and 5780 Tigon3 chips, and thus we can remove the workaround code from the tg3.c driver. Signed-off-by: David S.

Users are only running into this now because distros are now using 2.6.23 and I must have messed up when I tested the change. For receive, we now do our own calculation of how much to pull from the skb (variable length L2TP header) rather than using skb_transport_offset(). Also, if the skb isn't a data packet, it must be passed back to UDP with skb->data pointing to the UDP header. For transmit, make sure skb->sk is set up because ip_queue_xmit() needs it.

After the mac80211 patch to make the simple algorithm built-in, it would always be simple. This has always been a bug in iwlwifi. This fixes it by requesting that mac80211 selects the right rate control algorithm. Signed-off-by: Johannes Berg Signed-off-by: John W.

Commit bea3348e (the NAPI changes) made sungem unconditionally enable NAPI when resuming and unconditionally disable when suspending, this, however, makes napi_disable() hang when suspending when the interface was taken down before suspend because taking the interface down also disables NAPI. This patch makes touching the napi struct in suspend/resume code paths depend on having the interface up, thereby fixing the hang on suspend. The patch also moves the napi_disable() in gem_close() under the lock so that the NAPI state is always modified atomically together with the "opened" variable.

The tg3 driver has code to detect this condition and resets the device during initialization. On 5761 devices, device resets involve sending a driver state update message to the APE on the 5761. However, during this initialization stage, communications to the APE registers have not yet been set up. The driver then dereferences a NULL pointer and crashes the machine. The fix is to move the APE register access setup earlier in the initialization code to cover this condition. Signed-off-by: Matt Carlson Signed-off-by: Michael Chan Signed-off-by: David S.

This happens because of a hardware bug in the new CPMU. During normal operation, the MAC depends on the PHY clock being available. When the PHY is powered down, the clock the MAC depends on is disabled. The fix is to switch the MAC clock to an alternate source before powering down the PHY, and to restore the MAC clock to the PHY source upon device resume.

This was not an error but the change simplifies debugging of address-space mappings. - Made myPrevRxDesc local to e100_rx since it was only used there. Fixed out of memory handling in e100_rx. If dev_alloc_skb() fails persistently the system is hosed anyway but at least it won't loop in an interrupt handler. - Correct some code formatting issues. - Add defines SET_ETH_ENABLE_LEDS, SET_ETH_DISABLE_LEDS and SET_ETH_AUTONEG used in new cris v10 ethernet driver.

Heikki Orsila reports that it causes a regression: "Doing nc host port < /dev/zero on a sending machine (not skge) to an skge machine that is receiving: nc -l -p port >/dev/null with ~60 MiB/s speed, causes the interface go malfunct. A slow transfer doesn't cause a problem." See http://bugzilla.kernel.org/show_bug.cgi?id=9321 for some more information. There is a workaround (also reported by Heikki): "After some fiddling, I noticed that not changing the register write order on patch: + skge_write32(hw, RB_ADDR(q, RB_END), end); skge_write32(hw, RB_ADDR(q, RB_WP), start); skge_write32(hw, RB_ADDR(q, RB_RP), start); - skge_write32(hw, RB_ADDR(q, RB_END), end); fixes the visible effect.. Possibly not the root cause of the problem, but changing the order back fixes networking here." but that has yet to be ack'ed or tested more widely, so the whole problem-causing commit gets reverted until this is resolved properly.

From: Wagner Ferenc Also remove trailing spaces from multivalued files. This fixes output like for example: $ od -c /sys/class/net/bond0/bonding/slaves 0000000 e t h - l e f t e t h - r i g 0000020 h t \n \0 0000025 It mostly entails deleting '+1'-s after sprintf() calls: the return value of sprintf is the number of characters printed, without the closing NUL, ie. exactly what the sysfs interface requires. The three multivalue cases are different, because they also have to swallow back a trailing space.

Originally submitted by "Glenn Griffin" ; modified by Jay Vosburgh to move setting of hash policy out of line, tweak the documentation update and add version update to 3.2.2. Glenn's original comment follows: Included is a patch for a new xmit_hash_policy for the bonding driver that selects slaves based on MAC and IP information. This is a middle ground between what currently exists in the layer2 only policy and the layer3+4 policy. This policy strives to be fully 802.3ad compliant by transmitting every packet of any particular flow over the same link. As documented the layer3+4 policy is not fully compliant for extreme cases such as ip fragmentation, so this policy is a nice compromise for environments that require full compliance but desire more than the layer2 only policy.

Packets can be left in the RX ring if the NAPI budget is reached. This is caused by storing the latest rx index at the beginning of bnx2_rx_int(). We may not process all the work up to this index if the budget is reached and so some packets in the RX ring may rot when we later check for more work using this stored rx index. The fix is to not store this latest hw index and only store the processed rx index. We use a new function bnx2_get_hw_rx_cons() to fetch the latest hw rx index.

The receive MAC FIFO would become stuck during testing with high traffic. One port of the 88E8062 would lockup, while the other port remained functional. Re-inserting the sky2 module would not fix the problem - only a power cycle would. I looked over Marvell's most recent sk98lin driver and it looks like they had a "workaround" for the Yukon XL that the sky2 doesn't have yet. The sk98lin driver disables the RX MAC FIFO flush feature for all revisions of the Yukon XL. According to skgeinit.c of the sk98lin driver, "Flushing must be enabled (needed for ASF see dev. #4.29), but the flushing mask should be disabled (see dev. #4.115)". Nice.

That's a long-standing bug, BTW - see http://lkml.org/lkml/2004/2/27/180 for example. What happens is that card gets VLAN id table populated by byteswapped values on little-endian boxen (so 257 works as expected, 256 and 258 do not, etc.). Bug is easily reproduced, patch fixes it.

(2) The rfkill structure was initialized after the LED initialization. (3) There was a minor memory leak if the radio LED structure was inited. Once the above problems were fixed, additional difficulties were noted: (4) The radio LED was in the wrong state at startup. (5) The radio switch had to be manipulated twice for each state change. (6) A circular mutex locking situation existed. (7) If rfkill-input is built as a module, it is not automatically loaded. This patch fixes all of the above.

Then it feeds the entire page back to nvram. It should be storing the words it had read as little-endian, not as host-endian. Note that tg3_set_eeprom() does exactly that for padding the same data to full words before it gets passed down to tg3_nvram_write_block() and then to tg3_nvram_write_block_unbuffered(). Moreover, when we get to sending the entire thing back to nvram, we go through it word-by-word, doing essentially writel(swab32(le32_to_cpu(word)), ...) so if we want them to reach the card in host-independent endianness, we'd better really have all that buffer filled with fixed-endian. For user-supplied part we obviously do have that (it's an array of octets memcpy'd in), ditto for padding of user-supplied part to word boundaries (taken care of in tg3_set_eeprom()). The rest of the buffer gets filled by tg3_nvram_write_block_unbuffered() and it would damn better be consistent with that (and with tg3_get_eeprom(), while we are at it - there we also convert the words read from nvram to little-endian before returning the buffer to user). The bug should get triggered on big-endian boxen when set_eeprom is done for less than entire page. Then the words that should've been unaffected at all will actually get byteswapped in place in nvram. Signed-off-by: Al Viro Signed-off-by: David S.

Here's proposed fix for RX checksum handling in cassini; it affects little-endian working with half-duplex gigabit, but obviously needs testing on big-endian too. The problem is, we need to convert checksum to fixed-endian *before* correcting for (unstripped) FCS. On big-endian it won't matter (conversion is no-op), on little-endian it will, but only if FCS is not stripped by hardware; i.e. in half-duplex gigabit mode when ->crc_size is set. cassini.c part is that fix, cassini.h one consists of trivial endianness annotations. With that applied the sucker is endian-clean, according to sparse. Signed-off-by: Al Viro Signed-off-by: David S.

Miller" Date: Fri, 4 Jan 2008 23:54:06 -0800 Subject: [NIU]: Fix potentially stuck TCP socket send queues. It is possible for the TX ring to have packets sit in it for unbounded amounts of time. The only way to defer TX interrupts in the chip is to periodically set "mark" bits, when processing of a TX descriptor with the mark bit set is complete it triggers the interrupt for the TX queue's LDG. A consequence of this kind of scheme is that if packet flow suddenly stops, the remaining TX packets will just sit there. If this happens, since those packets could be charged to TCP socket send queues, such sockets could get stuck. The simplest solution is to divorce the socket ownership of the packet once the device takes the SKB, by using skb_orphan() in niu_start_xmit(). In hindsight, it would have been much nicer if the chip provided two interrupt sources for TX (like basically every other ethernet chip does). Namely, keep the "mark" bit, but also signal the LDG when the TX queue becomes completely empty. That way there is no need to have a deadlock breaker like this. Signed-off-by: David S.

Miller" Date: Mon, 7 Jan 2008 20:53:33 -0800 Subject: [NET]: Fix drivers to handle napi_disable() disabling interrupts. When we add the generic napi_disable_pending() breakout logic to net_rx_action() it means that napi_disable() can cause NAPI poll interrupt events to be disabled. And this is exactly what we want. If a napi_disable() is pending, and we are looping in the ->poll(), we want ->poll() event interrupts to stay disabled and we want to complete the NAPI poll ASAP. When ->poll() break out during device down was being handled on a per-driver basis, often these drivers would turn interrupts back on when '!netif_running()' was detected. And this would just cause a reschedule of the NAPI ->poll() in the interrupt handler before the napi_disable() could get in there and grab the NAPI_STATE_SCHED bit. The vast majority of drivers don't care if napi_disable() might have the side effect of disabling NAPI ->poll() event interrupts. In all such cases, when a napi_disable() is performed, the driver just disabled interrupts or is about to. However there were three exceptions to this in PCNET32, R8169, and SKY2. To fix those cases, at the subsequent napi_enable() points, I added code to ensure that the ->poll() interrupt events are enabled in the hardware. Signed-off-by: David S.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For cards that initially have the MAC address stored in reverse order, the forcedeth driver uses a flag to signal whether the address was already corrected, so that it is not reversed again on a subsequent probe. Unfortunately this flag, which is stored in a register of the card, seems to get lost during suspend, resulting in the MAC address being reversed again. To fix that, the MAC address needs to be written back in reversed order before we suspend and the flag needs to be reset. The flag is still required because at least kexec will never write back the reversed address and thus needs to know what state the card is in. Signed-off-by: Björn Steinbrink Signed-off-by: David S.

This cleans up some unnecessary byte-swapping while setting up tx and interpreting rx desc. The 64 bit rx status data should be converted to host endian format only once and the macros just need to extract bitfields. This saves a spate of interrupts on pseries blades caused by buggy (non) processing rx status ring.

When a VLAN-tagged frame arrives, the hardware passes it, but bad things happen because the buffer is too small. This patch fixes that. Thanks to David Harris for reporting the bug and testing the fix.

Miller" Date: Fri, 18 Jan 2008 04:21:39 -0800 Subject: [NET]: Fix interrupt semaphore corruption in Intel drivers. Several of the Intel ethernet drivers keep an atomic counter used to manage when to actually hit the hardware with a disable or an enable. The way the net_rx_work() breakout logic works during a pending napi_disable() is that it simply unschedules the poll even if it still has work. This can potentially leave interrupts disabled, but that is OK because all of the drivers are about to disable interrupts anyways in all such code paths that do a napi_disable(). Unfortunately, this trips up the semaphore used here in the Intel drivers. If you hit this case, when you try to bring the interface back up it won't enable interrupts. A reload of the driver module fixes it of course. So what we do is make sure all the sequences now go: napi_disable(); atomic_set(&adapter->irq_sem, 0); *_irq_disable(); which makes sure the counter is always in the correct state.

With nested devices this may lead to a use-after-free despite the use of for_each_netdev_safe() in case the upper device is next in the device list and is destroyed by the NETDEV_UNREGISTER notifier. The easy fix is to restart scanning the device list after removing a device. Alternatively we could add new devices to the front of the list to avoid having dependant devices follow the device they depend on. A third option would be to only restart scanning if dev->iflink of the next device matches dev->ifindex of the current one. For now this seems like the safest solution. With this patch, the veth rtnl_link_ops unregistration can use rtnl_link_unregister() directly since it now also handles destruction of multiple devices at once.

The change made transformations like turning: "srom + 34" into "(__le32 *)srom + 34/4" which doesn't work because 4 does not divide evenly into 34 so we're using a different pointer offset than in the original code.

That, in turn, drastically simplifies the code, and drops down line count. As an additional bonus, now there is no need to register MDIO bus for each PHY, all emulated PHYs placed on the platform fixed MDIO bus. There is also no more need to pre-allocate PHYs via .config option, this is all now handled dynamically.
