phy_start_machine — start PHY state machine tracking
void phy_start_machine ( | struct phy_device * phydev, |
void (*handler)
(struct net_device *)); |
The PHY infrastructure can run a state machine
which tracks whether the PHY is starting up, negotiating,
etc. This function starts the timer which tracks the state
of the PHY. If you want to be notified when the state changes,
pass in the callback handler, otherwise, pass NULL. If you
want to maintain your own state machine, do not call this
function.
