From: Roland Vossen <rvossen@xxxxxxxxxxxx>
Transmit can only be muted if the mac core is enabled. When brcms_b_init()
is called, the mac core is suspended. Brcms_b_init() calls a transmit mute
function that requires an enabled mac core. This code path is never taken,
but would have been taken in subsequent patches.
