int genphy_config_aneg

(

struct phy_device *

phydev

)

genphy_config_aneg - restart auto-negotiation or write BMCR : target phy_device struct

Description: If auto-negotiation is enabled, we configure the advertising, and then restart auto-negotiation. If it is not enabled, then we write the BMCR.

Definition at line 754 of file phy_device.c.

int genphy_read_status

(

struct phy_device *

phydev

)

genphy_read_status - check the link status and update current link state : target phy_device struct

Description: Check the link, then figure out the current state by comparing what we advertise with what the link partner advertises. Start by checking the gigabit possibilities, then move on to 10/100.

Definition at line 962 of file phy_device.c.

int genphy_update_link

(

struct phy_device *

phydev

)

genphy_update_link - update link status in : target phy_device struct

Description: Update the value in phydev->link to reflect the current link value. In order to do this, we need to read the status register twice, keeping the second value.

Definition at line 795 of file phy_device.c.

struct phy_device* get_phy_device ( struct mii_bus *  bus, int  addr, bool  is_c45  )

read

get_phy_device - reads the specified PHY device and returns its struct : the target MII bus : PHY address on the MII bus : If true the PHY uses the 802.3 clause 45 protocol

Description: Reads the ID registers of the PHY at on the , then allocates and returns the phy_device to represent it.
