Hi everyone,
I'm sorry to bother you. But I was confused.
The IP ID check (flush_id) in inet_gro_receive is only used by tcp_gro_receive, and in tcp_gro_receive we have tcphdr check to ensure the order of skbs, like below:
flush |= (__force int)(th->ack_seq ^ th2->ack_seq); flush |= (ntohl(th2->seq) + skb_gro_len(p)) ^ ntohl(th->seq);
So if I remove the IP ID check in inet_gro_receive, there will be a problem ? And under what circumstances ?
Thanks. Xiaojun.
