Eric Dumazet 0b1605e45c gro: take care of DODGY packets
[ Upstream commit 7871f54e3d ]

Jaroslav reported a recent throughput regression with virtio_net
caused by blamed commit.

It is unclear if DODGY GSO packets coming from user space
can be accepted by GRO engine in the future with minimal
changes, and if there is any expected gain from it.

In the meantime, make sure to detect and flush DODGY packets.

Fixes: 5eddb24901 ("gro: add support of (hw)gro packets to gro stack")
