--- Comment #6 from Vladislav Shabanov <vlad.shabanov@gmail.com> ---
(In reply to VVD from comment #5)
Thanks. I applied all this -xxx options.=20

Interestingly than the NIC hungs exactly after I executed this command line.
Then I executed=20
$ ifconfig igb0 -rxcsum -rxcsum6 -txcsum -txcsum6 -tso -lro -vlanmtu -vlanh=
wtag
-vlanhwfilter vlanhwtso

and it hungs again. I tried one more time with '-vlanhwtso' and it hungs on=
ce
more.

Thanks to VVD, now I can reproduce the bug manually. =D0=A1=D0=BF=D0=B0=D1=
=81=D0=B8=D0=B1=D0=BE :)
