2011-04-27sctp: cache the ipv6 source after route lookupVlad Yasevich
The ipv6 routing lookup does give us a source address, but instead of filling it into the dst, it's stored in the flowi. We can use that instead of going through the entire source address selection again. Also the useless ->dst_saddr member of sctp_pf is removed. And sctp_v6_dst_saddr() is removed, instead by introduce sctp_v6_to_addr(), which can be reused to cleanup some dup code.

2011-04-27ixgbe: do not clear FCoE DDP error status for received ABTSYi Zou
The ddp->err is initialized to be 1 to make sure outstanding DDP context is guaranteed to be invalidated when HW is not auto-invalidating it. However, in case of receiving ABTS response for a DDPed I/O, the ddp->err was cleared, bypassing the invalidating of the DDP context from upper protocol stack when ixgbe_fcoe_ddp_put() is called.

2011-04-25bonding: move processing of recv handlers into handle_frame()Jiri Pirko
Since now when bonding uses rx_handler, all traffic going into bond device goes thru bond_handle_frame. So there's no need to go back into bonding code later via ptype handlers. This patch converts original ptype handlers into "bonding receive probes". These functions are called from bond_handle_frame and they are registered per-mode. Note that vlan packets are also handled because they are always untagged thanks to vlan_untag() Note that this also allows arpmon for eth-bond-bridge-vlan topology.

2011-04-24r8169: don't request firmware when there's no userspace.François Romieu
The firmware is cached during the first successfull call to open() and released once the network device is unregistered. The driver uses the cached firmware between open() and unregister_netdev(). So far the firmware is optional : a failure to load the firmware does not prevent open() to success. It is thus necessary to 1) unregister all 816x / 810[23] devices and 2) force a driver probe to issue a new firmware load.

2011-04-22netconsole: fix deadlock when removing net driver that netconsole is using (v2)Neil Horman
A deadlock was reported to me recently that occured when netconsole was being used in a virtual guest. If the virtio_net driver was removed while netconsole was setup to use an interface that was driven by that driver, the guest deadlocked. No backtrace was provided because netconsole was the only console configured, but it became clear pretty quickly what the problem was. In netconsole_netdev_event, if we get an unregister event, we call __netpoll_cleanup with the target_list_lock held and irqs disabled. __netpoll_cleanup can, if pending netpoll packets are waiting call cancel_delayed_work_sync, which is a sleeping path. the might_sleep call in that path gets triggered, causing a console warning to be issued. The netconsole write handler of course tries to take the target_list_lock again, which we already hold, causing deadlock. The fix is pretty striaghtforward. Simply drop the target_list_lock and re-enable irqs prior to calling __netpoll_cleanup, the re-acquire the lock, and restart the loop. Confirmed by myself to fix the problem reported.

The commit 609ff3b ("be2net: add code to display temperature of ASIC") adds support to display temperature of ASIC but there is missing increment of work_counter in be_worker. Because of this 1) the function be_cmd_get_die_temperature is called every 1 second instead of every 32 seconds 2) be_cmd_get_die_temperature is called, although it is not supported. This patch fixes this bug. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-04-21ipv6: Remove hoplimit initialization to -1Thomas Egerer
The changes introduced with git-commit a02e4b7d ("ipv6: Demark default hoplimit as zero.") missed to remove the hoplimit initialization. As a result, ipv6_get_mtu interprets the return value of dst_metric_raw (-1) as 255 and answers ping6 with this hoplimit. This patche removes the line such that ping6 is answered with the hoplimit value configured via sysctl. Signed-off-by: Thomas Egerer <thomas.egerer@secunet.com> Signed-off-by: David S.

2011-04-21net: fix hw_features ethtool_ops->set_flags compatibilityMichał Mirosław
__ethtool_set_flags() was not taking into account features set but not user-toggleable. Since GFLAGS returns masked dev->features, EINVAL is returned when passed flags differ to it, and not to wanted_features.

2011-04-21tg3: Add macro for SMDSP togglingMatt Carlson
A common AUX CTRL operation in the driver is to enable and disable the SMDSP. This patch consolidates the code so that the details of the operation are in one place. This patch also adds code to make sure the SMDSP is enabled before executing code that relies on it.

2011-04-21tg3: Only allow phy ioctls while netif_runningMatt Carlson
When tg3 was new, phy accesses through ioctl were allowable at any time. Then, the driver started shutting down the phy when the device was closed. Phy accesses would be allowed when the driver first attached to the device, but then would be forbidden after the device had been up'd and down'd. After that, management firmware made it illegal to access the phy unless the driver "owned" the device. Now that most firmware is being moved over to the APE, it is less clear when phy accesses are safe. While it is possible to attempt to identify these conditions and code the driver to navigate through the pitfalls, it could be perplexing to the admin why phy accesses work in some cases and not others. This patch brings some uniformity to the problem by only allowing phy accesses while the driver has control of the device.

2011-04-21tg3: Adjust rx prod ring bd replenish thresholdsMatt Carlson
The oldest tg3 devices had large rx producer ring BD caches. Back then, it made sense to make the BD cache replenish threshold only a function of the number of rx buffers posted by the driver. Since then, the BD cache sizes have shrunk to 25% of their original size and, in some cases, the ring sizes have quadrupled in size. Under such conditions, static BD cache replenish thresholds no longer match the hardware constraints. This patch attempts to factor in the BD cache size into the bd cache replenish strategy, taking the existing hardware bugs into account.

The 5717, 5718, 5719 A0, and 5720 A0 has a bug where the rx_discards statistic counter will increment when dropping unwanted multicast frames. This patch works around the problem by attempting to recreate the data using other means. The resulting value will not be accurate, but it can still serve as a problem indicator.
