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. Add a similar new helper to cover both of these. It can and will be used to avoid retpoline overhead when IP header lies behind another offloaded proto. Signed-off-by: Alexander Lobakin <alobakin@pm.me> Signed-off-by: David S.
