Hi Greg, hi Sasha

As per https://bugzilla.kernel.org/show_bug.cgi?id=194569 applying the
commit 0b9aefea8600 ("tcp: minimize false-positives on TCP/GRO check")
would reduce the false-positives. dcb17d22e1c2 was introduced in v4.9.

Thoughs? Can you consider applying it for 4.9.y?

Regards,
Salvatore
