Subject: bridge: fdb: add flush [no]offloaded entry matching
X-Git-Tag: v6.0.0~40^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4a4e32a92b56a94c9192dbdcb6e504edf58d11d6;p=thirdparty%2Fiproute2.git

bridge: fdb: add flush [no]offloaded entry matching

Add flush support to match entries with or without (if "no" is
prepended) offloaded flag.

Examples:
$ bridge fdb flush dev br0 offloaded
This will delete all offloaded entries in br0's fdb table.

$ bridge fdb flush dev br0 nooffloaded
This will delete all entries except the ones with offloaded flag in
br0's fdb table.
