-Subject: [PATCH 618/660] net: sfp: move sfp sub-state machines into separate
- functions
-
-Move the SFP sub-state machines out of the main state machine function,
-in preparation for it doing a bit more with the device state. By doing
-so, we ensure that our debug after the main state machine is always
-printed.
