Eric Dumazet cbb3100329 net: check dev->gso_max_size in gso_features_check() 
[ Upstream commit 24ab059d2ebd62fdccc43794796f6ffbabe49ebc ]

Some drivers might misbehave if TSO packets get too big.

GVE for instance uses a 16bit field in its TX descriptor,
and will do bad things if a packet is bigger than 2^16 bytes.

Linux TCP stack honors dev->gso_max_size, but there are
other ways for too big packets to reach an ndo_start_xmit()
handler : virtio_net, af_packet, GRO...

Add a generic check in gso_features_check() and fallback
to GSO when needed.

gso_max_size was added in the blamed commit.

Fixes: 82cc1a7a5687 ("[NET]: Add per-connection option to set max TSO frame size")
