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