Willem also pointed that out, and I agree. I'll post a v5 and move this
functionality to gro.c. Currently, gro_network_flush will be called from
tcp_gro_receive and in a separate series I'll fix the bug by calling
gro_network_flush in skb_gro_receive or adding it to
udp_gro_receive_segment - whichever is better.

This patch is meaningful by itself - removing checks against non-relevant
packets and making the flush/flush_id checks in a single place.
