The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
phy_init_eee – init and check the EEE feature Synopsis int phy_init_eee(struct phy_device *phydev, bool clk_stop_enable); Arguments phydev target phy_device struct clk_stop_enable PHY may stop the clock during LPI Description it checks if the Energy-Efficient Ethernet (EEE) is supported by looking at the MMD registers 3.20 and 7.60/61 and it programs the MMD register 3.0 setting…
phy_get_eee_err – report the EEE wake error count Synopsis int phy_get_eee_err(struct phy_device *phydev); Arguments phydev target phy_device struct Description it is to report the number of time where the PHY failed to complete its normal wake sequence. Copyright
phy_find_valid – find a PHY setting that matches the requested features mask Synopsis unsigned int phy_find_valid(unsigned int idx, u32 features); Arguments idx The first index in settings[] to search features A mask of the valid settings Description Returns the index of the first valid setting less than or equal to the one pointed to by…
phy_find_setting – find a PHY settings array entry that matches speed & duplex Synopsis unsigned int phy_find_setting(int speed, int duplex); Arguments speed speed to match duplex duplex to match Description Searches the settings array for the setting which matches the desired speed and duplex, and returns the index of that setting. Returns the index of…
phy_find_first – finds the first PHY device on the bus Synopsis struct phy_device *phy_find_first(struct mii_bus *bus); Arguments bus the target MII bus Copyright
phy_ethtool_sset – generic ethtool sset function, handles all the details Synopsis int phy_ethtool_sset(struct phy_device *phydev, struct ethtool_cmd *cmd); Arguments phydev target phy_device struct cmd ethtool_cmd Description A few notes about parameter checking: – We don’t set port or transceiver, so we don’t care what they were set to. – phy_start_aneg will make sure forced settings…
phy_ethtool_set_eee – set EEE supported and status Synopsis int phy_ethtool_set_eee(struct phy_device *phydev, struct ethtool_eee *data); Arguments phydev target phy_device struct data ethtool_eee data Description it is to program the Advertisement EEE register. Copyright
phy_ethtool_get_eee – get EEE supported and status Synopsis int phy_ethtool_get_eee(struct phy_device *phydev, struct ethtool_eee *data); Arguments phydev target phy_device struct data ethtool_eee data Description it reportes the Supported/Advertisement/LP Advertisement capabilities. Copyright
phy_error – enter HALTED state for this PHY device Synopsis void phy_error(struct phy_device *phydev); Arguments phydev target phy_device struct Description Moves the PHY to the HALTED state in response to a read or write error, and tells the controller the link is down. Must not be called from interrupt context, or while the phydev->lock is…
phy_enable_interrupts – Enable the interrupts from the PHY side Synopsis int phy_enable_interrupts(struct phy_device *phydev); Arguments phydev target phy_device struct Copyright
phy_driver_register – register a phy_driver with the PHY layer Synopsis int phy_driver_register(struct phy_driver *new_driver, struct module *owner); Arguments new_driver new phy_driver to register owner module owning this PHY Copyright
phy_disconnect – disable interrupts, stop state machine, and detach a PHY device Synopsis void phy_disconnect(struct phy_device *phydev); Arguments phydev target phy_device struct Copyright
phy_disable_interrupts – Disable the PHY interrupts from the PHY side Synopsis int phy_disable_interrupts(struct phy_device *phydev); Arguments phydev target phy_device struct Copyright
phy_device_remove – Remove a previously registered phy device from the MDIO bus Synopsis void phy_device_remove(struct phy_device *phydev); Arguments phydev phy_device structure to remove Description This doesn’t free the phy_device itself, it merely reverses the effects of phy_device_register. Use phy_device_free to free the device after calling this function. Copyright
phy_device_register – Register the phy device on the MDIO bus Synopsis int phy_device_register(struct phy_device *phydev); Arguments phydev phy_device structure to be added to the MDIO bus Copyright
phy_detach – detach a PHY device from its network device Synopsis void phy_detach(struct phy_device *phydev); Arguments phydev target phy_device struct Description This detaches the phy device from its network device and the phy driver, and drops the reference count taken in phy_attach_direct. Copyright
phy_connect_direct – connect an ethernet device to a specific phy_device Synopsis int phy_connect_direct(struct net_device *dev, struct phy_device *phydev, void (*handler)(struct net_device *), phy_interface_t interface); Arguments dev the network device to connect phydev the pointer to the phy device handler callback function for state change notifications interface PHY device’s interface Copyright
phy_connect – connect an ethernet device to a PHY device Synopsis struct phy_device *phy_connect(struct net_device *dev, const char *bus_id, void (*handler)(struct net_device *), phy_interface_t interface); Arguments dev the network device to connect bus_id the id string of the PHY device to connect handler callback function for state change notifications interface PHY device’s interface Description Convenience…
phy_config_interrupt – configure the PHY device for the requested interrupts Synopsis int phy_config_interrupt(struct phy_device *phydev, u32 interrupts); Arguments phydev the phy_device struct interrupts interrupt flags to configure for this phydev Description Returns 0 on success or < 0 on error. Copyright
phy_clear_interrupt – Ack the phy device’s interrupt Synopsis int phy_clear_interrupt(struct phy_device *phydev); Arguments phydev the phy_device struct Description If the phydev driver has an ack_interrupt function, call it to ack and clear the phy device’s interrupt. Returns 0 on success or < 0 on error. Copyright
