I wonder if it would be possible to do something in the netlink framework, like
NETLINK_LISTEN_ALL_NSID.
Having some ancillary data at the netlink socket level and a function like
nlsock_net() (instead of sock_net()) to get the corresponding netns.
With that, it would be possible, in a generci way, to support this feature for
all netlink family.
