Ananda, Herbert Xu recently found a problem in the TCP stack input path for LRO capable receive paths.
The issue is that the receive MSS estimator in tcp_measure_rcv_mss() uses skb->len for the MSS estimation. This is wrong for LRO frames. Herbert noticed this using Xen which pused TSO frames on output back into the destination TCP stack on input so it looks exactly like LRO. His fix to tcp_measure_rcv_mss() is to use skb_shared_info(skb)->gso_size if it is non-zero, else skb->len, in the assignment to "len". So could you please make the S2io driver LRO path set skb_shared_info(skb)->gso_size appropriately? Probably the easiest is to use the length of the first frag of a multiple frag LRO sequence. Also, could we have a linux/MAINTAINERS entry added for the S2io driver?
