Bug#664461: [squeeze] atl1c: AR8152: "transmit queue 0 timed out" and network is unusable until reset
Hi Jonathan
For driver atl1c, we add many patches recently. Please sync with the kernel, the last patch is
80bcb4238dd858d atl1c: remove PHY polling from atl1c_change_mtu
Most of the time, the issue of tx q0 timeout is caused by wrong HW configuration and bad cable condition.
It will cause the PHY/cable link unstable, and the driver doesn't correctly reset the DMA engine and clear all
Pending tx-packet while link down --- and timeout issue will appear.
Thanks
Xiong
