Implement MAC Flush for BD or Interface from the L2FIB
Allow non-static MACs in the L2FIB which is associated with an interface or a bridge domain (BD) be flushed. MAC flush are initiated automatically when an interface is removed from a BD or when a BD is deleted. MAC flush can also be invoked manually via the following CLI: l2fib mac-flush interface <if-name> l2fib mac-flush bridge-domain <bd-id> Change-Id: Ie33243622834810a765f48ebcd22bdb8e8fc87a4 Signed-off-by: John Lo <loj@cisco.com>
