[PATCH net-next V2 1/2] net: introduce skb_coalesce_rx_frag()
...skb_frag_unref(frag);
But I do think this is best done in the caller.
In virtio_net this would be a :
put_page(page);
In tcp stack we do almost the same, but we take the reference on the
page if we could not coalesce with prio frag, instead of doing a get and
put in the other case.
if (can_coalesce) {
skb_frag_size_add(&skb_shinfo(skb)->frags[i - 1], copy);
} else {
get_page(page);
skb_fill_page_desc(skb, i, page, offset, copy);
}

[PATCH net-next V2 1/2] net: introduce skb_coalesce_rx_frag()
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.

[RFC V7 PATCH 0/7] enable tx interrupts for virtio-net
Hi:
This is a new version of trying to enable tx interrupts for
virtio-net.
We used to try to avoid tx interrupts and orphan packets before
transmission for virtio-net. This breaks socket accounting and can
lead serveral other side effects e.g:
- Several other functions which depends on socket accounting can not
work correctly (e.g TCP Small Queue)
- No tx completion which make BQL or packet

[PATCH RFC v4 net-next 0/5] virtio_net: enabling tx interrupts
Hello:
We used to orphan packets before transmission for virtio-net. This breaks
socket accounting and can lead serveral functions won't work, e.g:
- Byte Queue Limit depends on tx completion nofication to work.
- Packet Generator depends on tx completion nofication for the last
transmitted packet to complete.
- TCP Small Queue depends on proper accounting of sk_wmem_alloc to work.
