Subject: [PATCH 2/3] net: calxedaxgmac: add uc and mc filter addresses in promiscuous mode

From: Rob Herring <rob.herring@...xeda.com>

Even in promiscuous mode, we need to add filter addresses for correct
operation. This fixes silent failures when using a bridge and adding
addresses using the "bridge fdb add" command.
