net: phy: export phy_queue_state_machine
We face the issue that link change interrupt and link status may be
reported by different PHY layers. As a result the link change
interrupt may occur before the link status changes.
Export phy_queue_state_machine to allow PHY drivers to specify a
delay between link status change interrupt and link status check.
v2:
- change jiffies parameter type to unsigned long
