Subject: [PATCH 629/660] net: sfp: ensure TX_FAULT has deasserted before
|
|
probing the PHY
|
|
|
|
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.
