...ish current avail idx as used event. This series fixes several issues of original rfc pointed out by Michael. Smoking test is done, and will do complete netperf test. Send the seires for early review. Thanks Jason Wang (6): virtio: make sure used event never go backwards virtio: introduce virtio_enable_cb_avail() virtio-net: small optimization on free_old_xmit_skbs() virtio-net: return the number of packets sent in free_old_xmit_skbs() virtio-net: enable tx interrupt virtio-net: enable tx interrupt only for the final skb in the chain drivers/net/virtio_net.c | 125 ++++++++++++++++++++++++++...
