Generally good idea but formatting is off.
missing whitespace after mac address also LOWERLAYERDOWN is too long.

$ ./ip/ip -br li show
lo               UNKNOWN  00:00:00:00:00:00<LOOPBACK,UP,LOWER_UP>
eth1             DOWN     00:25:90:86:b3:6b<BROADCAST,MULTICAST>
eth0             UP       00:25:90:86:b3:6a<BROADCAST,MULTICAST,UP,LOWER_UP>
eth2             DOWN     00:1b:21:a0:e7:06<NO-CARRIER,BROADCAST,MULTICAST,UP>
