The brief format does not honer the master and type filters:
$ ip link show master vrf-mgmt
7: dummy0: <BROADCAST,NOARP,SLAVE> mtu 1500 qdisc noop master vrf-mgmt state
DOWN mode DEFAULT group default qlen 1000
link/ether 66:39:cc:2b:e9:bd brd ff:ff:ff:ff:ff:ff
$ ip -br link show master vrf-mgmt
lo UNKNOWN 00:00:00:00:00:00 <LOOPBACK,UP,LOWER_UP>
eth0 UP 08:00:27:de:14:c8
<BROADCAST,MULTICAST,UP,LOWER_UP>
eth1 UP 08:00:27:87:02:f1
<BROADCAST,MULTICAST,UP,LOWER_UP>
eth2 UP 08:00:27:61:1e:fd
<BROADCAST,MULTICAST,UP,LOWER_UP>
vrf-blue UNKNOWN a6:3f:09:34:7e:74 <NOARP,MASTER,UP,LOWER_UP>
vrf-red DOWN fe:a2:2d:e1:bc:ac <NOARP,MASTER>
dummy0 DOWN 66:39:cc:2b:e9:bd <BROADCAST,NOARP,SLAVE>
dummy1 DOWN 4a:4f:13:91:64:b1 <BROADCAST,NOARP,SLAVE>
dummy2 DOWN b2:4f:b6:cd:bd:a6 <BROADCAST,NOARP>
dummy3 DOWN 1e:06:3d:40:b8:c2 <BROADCAST,NOARP,SLAVE>
vrf-mgmt DOWN ce:b2:74:41:21:df <NOARP,MASTER>
With this patch the expected output is shown:
$ ip -br link show master vrf-mgmt
dummy0 DOWN 66:39:cc:2b:e9:bd <BROADCAST,NOARP,SLAVE>
