sis900: phy for FoxCon motherboard
dl2k: use DMA_48BIT_MASK constant
phy: mdiobus_register(): initialize all phy_map entries
sky2: ifdown kills irq mask
|
|
661FX7MI-S motherboard which uses the SiS 661FX chipset. The patch adds
an entry to mii_chip_info for the transceiver.
The PHY ids were found using the sis900_c_122.diff patch from
http://brownhat.org/sis900.html but that patch didn't solve the problem,
because the PHY at address 1 was already being chosen.
Without my patch, when bursts of packets arrive from other hosts on a
LAN, the interface dropped one roughly 10% of the time, causing
retransmits. There were fifth second pauses in refresh of large xterms,
and it made Netrek suck. I can provide further test data.
Workaround in lieu of patch is to use mii-tool to advertise
100baseTx-HD, then force renegotiation.
I wasn't able to identify the actual transceiver, so the description
field is a guess.
This patch is similar to Artur Skawina's patch:
http://marc.theaimsgroup.com/?l=linux-netdev&m=114297516729079&w=2
I'm not sure, but I wonder if it means the default behaviour should be
changed, so as to better handle future transceivers.
Diff is against 2.6.16.13.

tg3_run_loopback doesn't check that dev_alloc_skb() returns anything
useful.
Even if dev_alloc_skb() fails to return an skb to us we'll happily go
on and assume it did, so we risk dereferencing a NULL pointer. Much
better to fail gracefully by returning -ENOMEM than crashing here.

Need to make the edge-triggered workaround timer faster to get marginally
better peformance. The test_and_set_bit in schedule_prep() acts as a barrier

The problem here is that the bcm34xx driver and the ieee80211
stack do not agree on what channels are possible for 802.11a.
The ieee80211 stack only wants channels between 34 and 165, while
the bcm43xx driver accepts anything from 0 to 200. I made the
bcm43xx driver comply with the ieee80211 stack expectations, by
using the proper constants.

Fixes Rhine I cards disclosing fragments of previously transmitted frames
in new transmissions.
Before transmission, any socket buffer (skb) shorter than the ethernet
minimum length of 60 bytes was zero-padded. On Rhine I cards the data can
later be copied into an aligned transmission buffer without copying this
padding. This resulted in the transmission of the frame with the extra
bytes beyond the provided content leaking the previous contents of this
buffer on to the network.
Now zero-padding is repeated in the local aligned buffer if one is used.
Following a suggestion from the via-rhine maintainer, no attempt is made
here to avoid the duplicated effort of padding the skb if it is known that
an aligned buffer will definitely be used. This is to make the change
"obviously correct" and allow it to be applied to a stable kernel if
necessary. There is no change to the flow of control and the changes are
only to the Rhine I code path.
The patch has run on an in-service Rhine-I host without incident. Frames
shorter than 60 bytes are now correctly zero-padded when captured on a
separate host. I see no unusual stats reported by ifconfig, and no unusual
log messages.

The SET_NETDEV_DEV has to be done before a call to register_netdev. With
the new patch below, the device symlink for the platform device was
created. Unfortunately, after the 4 ls commands, the network connection

Add a reset_phy parameter to tg3_reset_hw() and tg3_init_hw(). With

during chip reset will cause a link down and bonding will not work
