 Add a Ethernet address filtering rule to the bridge on a specific interface.
+.Fa ifbr_name
+contains the name of the bridge device, and
+.Fa ifbr_ifsname
+contains the name of the bridge member interface.
+The
+.Fa ifbr_action
+field is one of
+.Fa BRL_ACTION_PASS
+or
+.Fa BRL_ACTION_BLOCK ,
+to pass or block matching frames respectively.
+The
+.Fa ifbr_flags
+specifies whether the rule should match on input, output, or both
+be using the flags
+.Fa BRL_FLAG_IN
+and
+.Fa BRL_FLAG_OUT .
+It also specifies whether either (or both) of the source and destination
+addresses should be matched by using the
+.Fa BRL_FLAG_SRCVALID
+and
+.Fa BRL_FLAG_DSTVALID
+flags.
+The
+.Fa ifbr_src
+field is the source address that triggers the rule (only considered if
+.Fa ifbr_flags
+has the
+.Fa BRL_FLAG_SRCVALID
+bit set).
+The
+.Fa ifbr_src
+field is the destination address that triggers the rule (only considered if
+.Fa ifbr_flags
+has the
+.Fa BRL_FLAG_DSTVALID
+bit set).
