Subject: Re: [PATCH net-next] gro: relax ID check in inet_gro_receive()

Reverting/deleting this code is going way too far.
Mark it experimental, but don't delete it.

This is (a) useful for continued development and experimentation and
(b) will likely be widely deployed (and here I don't mean by my
employer specifically, but mean in general by cloud/virtualization
companies and anyone else that cares about tunnel performance)
regardless of whether upstream linux decides to include it or not.

(Furthermore if the fw/driver is changed to increment inner IP ID
instead of outer IP ID, this will for the most part not be visible to
the end users, since the tunneling is usually internal to the
virtualization provider, and no-one besides their internal network
sees the external IP header.)
