implementation of IEEE 802.1Qbg in lldpad, part2
Hi,
This series of patches contains the second part of an initial implementation of
the IEEE 802.1Qbg standard: code for the exchange of VDP VSI TLVs between a
host with virtual machines and an adjacent switch.
VDP profiles consisting of mode,mgrid,typeid,typeidversion,instanceid,mac,vlan
can be given to lldpad with lldptool.

[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
