This function is in fact counting the ring slots required for responses. Separate the concepts of ring slots and skb frags make the code clearer, as now netfront and netback can have different MAX_SKB_FRAGS, slot and frag are not mapped 1:1 any more.

Sometimes we need to coalesce the rx frags to avoid frag list. One example is virtio-net driver which tries to use small frags for both MTU sized packet and GSO packet. So this patch introduce skb_coalesce_rx_frag() to do this. Cc: Rusty Russell <rusty at rustcorp.com.au> Cc: Michael S. Tsirkin <mst at redhat.com> Cc: Michael...

We need to drop the refcnt of page when we fail to allocate an skb for frag list, otherwise it will be leaked.

Hello, I would like to announce the semi-optimized oc_state_loop_filter_frag_rows It gains like 7% speedup. Unfortunately it has some issues: 1) wont compile on 64bit (I will fix it later hopefully) 2) is not yet fully optimized (instruction stalls) Here are the results.
