Subject: [PATCH iproute2-next 0/6] Allow to monitor 'all-nsid' with ip and ip xfrm


The goal of this series is to take advantage of the new netlink socket option:
NETLINK_LISTEN_ALL_NSID.

Here is an output example. vxlan10 is created in the current netns (netns0,
nsid 0) and then moved to another netns (netns1, nsid 1):

$ ip netns exec netns0 ip monitor all-nsid label
[nsid 0][NSID]nsid 1 (iproute2 netns name: netns1)
[nsid 0][NEIGH]??? lladdr 00:00:00:00:00:00 REACHABLE,PERMANENT
[nsid 0][LINK]5: vxlan10@...E: <BROADCAST,MULTICAST> mtu 1450 qdisc noop state DOWN group default
