TX_FAULT should be deasserted to indicate that the module has completed
its initialisation. This may include the on-board PHY, so wait until
the module has deasserted TX_FAULT before probing the PHY.
This means that we need an extra state to handle a TX_FAULT that
remains set for longer than t_init, since using the existing handling
state would bypass the PHY probe.
