Message

This patchset makes printing of vxlan details more consistent.

Before:
$ ip -d link show dev vxlan0
4: vxlan0: <BROADCAST,MULTICAST> mtu 1450 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether e6:a4:54:b2:34:85 brd ff:ff:ff:ff:ff:ff promiscuity 0  allmulti 0 minmtu 68 maxmtu 65535 
    vxlan id 42 group 239.1.1.1 dev enp2s0 srcport 0 0 dstport 4789 ttl auto ageing 300 udpcsum noudp6zerocsumtx noudp6zerocsumrx addrgenmode eui64 numtxqueues 1 numrxqueues 1 gso_max_size 64000 gso_max_segs 64 tso_max_size 64000 tso_max_segs 64 gro_max_size 65536 

After:
$ ip -d link show dev vxlan0
4: vxlan0: <BROADCAST,MULTICAST> mtu 1450 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether e6:a4:54:b2:34:85 brd ff:ff:ff:ff:ff:ff promiscuity 0  allmulti 0 minmtu 68 maxmtu 65535 
    vxlan id 42 group 239.1.1.1 dev enp2s0 srcport 0 0 dstport 4789 ttl auto ageing 300 addrgenmode eui64 numtxqueues 1 numrxqueues 1 gso_max_size 64000 gso_max_segs 64 tso_max_size 64000 tso_max_segs 64 gro_max_size 65536

And JSON output is more complete
$ ip -j -p -d link show dev vxlan0
