Which repo and branch did you look at? Ben's backport of changes
up to 80bcb4238dd8 ("atl1c: remove PHY polling from atl1c_change_mtu",
2012-04-30) is at
git://anonscm.debian.org/kernel/linux.git
branch
squeeze-driver-test
The patch that seemed to help Axel is
commit 7eb5862f477a
Author: Jie Yang <jie.y...@atheros.com>
Date: Tue Jun 1 00:28:12 2010 -0700
atl1c: Add AR8151 v2 support and change L0s/L1 routine
commit 8f574b35f22fbb9b5e5f1d11ad6b55b6f35f4533 upstream.
Add AR8151 v2.0 Gigabit 1000 support
Change jumbo frame size to 6K
Update L0s/L1 rountine
when link speed is 100M or 1G, set L1 link timer to 4 for
l1d_2 and l2c_b2
set L1 link timer to 7 for l2c_b, set L1 link timer to 0xF
for others.
Update atl1c_suspend routine
just refactory the function, add atl1c_phy_power_saving routine,
when Wake On Lan enable, this func will be called to save power,
it will reautoneg PHY to 10/100M speed depend on the link
partners link capability.
Update atl1c_configure_des_ring
do not use l2c_b default SRAM configuration.
That doesn't mean there aren't tx queue 0 timeouts in other situations
that that patch doesn't address, though.
Thanks,
Jonathan
