Re: BUG: TCPDUMP invalid cksum persists after disabling TCP cksum offload

Rick is correct. Disabling TX CKO also disable TSO. You can see that in
my ethtool output.

The results after disabling tcp cksum offload feature:
# ethtool -K eth1 tx off
Instead of this, can you try
# ethtool -K eth1 tso off
Doesn't TSO depend on TX CKO being enabled?  That is, if TX CKO were
disabled, shouldn't TSO have been implicitly disabled at the same time?
