net: fix address check in rtnl_fdb_del
Commit 6681712d67eef14c4ce793561c3231659153a320 vxlan: generalize forwarding tables relaxed the address checks in rtnl_fdb_del() to use is_zero_ether_addr(). This allows users to add multicast addresses using the fdb API. However, the check in rtnl_fdb_del() still uses a more strict is_valid_ether_addr() which rejects multicast addresses. Thus it is possible to add an fdb that can not be later removed. Relax the check in rtnl_fdb_del() as well. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S.
