{inet,ipv6}_gro_receive functions perform flush checks (ttl, flags, iph->id, ...) against all packets in a loop. These flush checks are relevant only to tcp flows, and as such they're used to determine whether the packets can be merged later in tcp_gro_receive.

These checks are not relevant to UDP packets.

These are network protocol coalescing invariants. Why would they be limited to certain transport protocols only?

Thanks for the review, I'll fix the typos. I replied to Eric's comment about the relevancy of these checks for UDP.
