Subject: [PATCH iproute2-next 7/8] bridge: fdb: support match on [no]router flag in flush command
Extend "fdb flush" command to match entries with or without (if "no" is
prepended) router flag.
Examples:
$ bridge fdb flush dev vx10 router
This will delete all fdb entries pointing to vx10 with router flag.
$ bridge fdb flush dev vx10 norouter
This will delete all fdb entries pointing to vx10, except the ones with
router flag.
