I was able to consistently reproduce this issue in Debian Wheezy by setting up
two Dell PowerEdge R620 servers directly connected and doing constant scp
transfer of large files back and forth while also setting the interface up &
down in a loop until it breaks (while [ true ]; do ip link set ${DEV} down;
sleep 1; ip link set ${DEV} up; sleep 9; done).
I have then updated the tg3 driver to version 3.137h, but the issue was still
reproducible.
I have tried RedHat 7.1 and it works fine (Kernel: 3.10.0-229.el7.x86_64, tg3
3.137).
Then I have tried Debian Jessie (kernel 3.16, tg3 3.137) and the issue is not
reproducible.
