[PATCH net-next 00/11] Vhost_net TX batching
Hi all:
This series tries to batch submitting packets to underlayer socket
through msg_control during sendmsg(). This is done by:
1) Doing userspace copy inside vhost_net
2) Build XDP buff
3) Batch at most 64 (VHOST_NET_BATCH) XDP buffs and submit them once
through msg_control during sendmsg().
4) Underlayer sockets can use XDP buffs directly when XDP is enalbed,
or build skb based on XDP
