Herbert Xu 9d8506cc2d gso: handle new frag_list of frags GRO packets ... Recently GRO started generating packets with frag_lists of frags. This was not handled by GSO, thus leading to a crash. Thankfully these packets are of a regular form and are easy to handle. This patch handles them in two ways. For completely non-linear frag_list entries, we simply continue to iterate over the frag_list frags once we exhaust the normal frags. For frag_list entries with linear parts, we call pskb_trim on the first part of the frag_list skb, and then process the rest of the frags in the usual way. This patch also kills a chunk of dead frag_list code that has obviously never ever been run since it ends up generating a bogus GSO-segmented packet with a frag_list entry. Future work is planned to split super big packets into TSO ones.
