along with a smallish description of what they do, fix that.

Each driver consists of a number of function pointers:
+ soft_reset: perform a PHY software reset
config_init: configures PHY into a sane state after a reset.
For instance, a Davicom PHY requires descrambling disabled.
probe: Allocate phy->priv, optionally refuse to bind.
PHY may not have been reset or had fixups run yet.
suspend/resume: power management
config_aneg: Changes the speed/duplex/negotiation settings
+ aneg_done: Determines the auto-negotiation result
read_status: Reads the current speed/duplex/negotiation settings
ack_interrupt: Clear a pending interrupt
+ did_interrupt: Checks if the PHY generated an interrupt
config_intr: Enable or disable interrupts
remove: Does any driver take-down
+ ts_info: Queries about the HW timestamping status
+ hwtstamp: Set the PHY HW timestamping configuration
+ rxtstamp: Requests a receive timestamp at the PHY level for a 'skb'
+ txtsamp: Requests a transmit timestamp at the PHY level for a 'skb'
+ set_wol: Enable Wake-on-LAN at the PHY level
+ get_wol: Get the Wake-on-LAN status at the PHY level
Of these, only config_aneg and read_status are required to be
assigned by the driver code. The rest are optional. Also, it is
