Subject: [PATCH iproute2-next 4/6] bridge: mdb: print filter mode when available

From: Nikolay Aleksandrov <nikolay@...dia.com>

Print the mdb entry's filter mode when it's available if the user
requested to show details (-d). It can be either include or exclude.
Currently it's kernel controlled and can't be changed by user-space.
