Thanks, Christopher. But I think my problem may does not related to
TSO issue. I have tried disable tso with "ifconfig igb(x) -tso" and
ovserved with "netstat -ihw 1", and found "oErrs" does not disappeared.

Hi Simon,
Try checking out the "9.2 ixgbe tx queue hang' thread here, and see if
it applies to you.

Hi,Lists:
I have got lots of "no buffer available" on 10-stable with igb
nic.
But em and bce works well. And I tried force igb to 4 or 8 queues and
set hw.igb.rx_process_limit="-1", but have nothing helped.
