   1 bgmac: fix internal switch initialization
   2
   3 Some devices (BCM4749, BCM5357, BCM53572) have internal switch that
   4 requires initialization. We already have code for this, but because
   5 of the typo in code it was never working. This resulted in network not
   6 working for some routers and possibility of soft-bricking them.
   7
   8 Use correct bit for switch initialization and fix typo in the define.
