The problem was vxlan wasn't doing sk_change_net on the created socket.
I'm testing that fix.
The long term fix is to change sock_create_kern() to take a 'struct net'
argument. This would avoid the trap of having to change the namespace.
Also several places using __sock_create() could use it.
L2TP still looks to have several namespace related issues.
