Hello,

Hi!

call_gro_receive() is used to limit GRO recursion, but it works only
with callback pointers.
There's a combined version of call_gro_receive() + INDIRECT_CALL_2()
in <net/inet_common.h>, but it doesn't check for IPv6 modularity.

AFAICS, ip6_offload is builtin even when IPv6 is a module, so the above
should not be needed.

Aww, you are right. I overlooked that since dev_gro_receive() still
use INDIRECT_CALL_INET(), though all GRO callbacks were made
built-in.

Seems like more code can be optimized, thanks!

Cheers,

Paolo
