Struct kernel::net::phy::Device

#[repr(transparent)]
pub struct Device(/* private fields */);

An instance of a PHY device.

Wraps the kernel’s struct phy_device.

A Device instance is created when a callback in Driver is executed. A PHY driver executes Driver’s methods during the callback.

Invariants

Referencing a phy_device using this struct asserts that you are in a context where all methods defined on this struct are safe to call.

Implementations

impl Device

pub fn phy_id(&self) -> u32

Gets the id of the PHY.

pub fn state(&self) -> DeviceState

Gets the state of PHY state machine states.

pub fn is_link_up(&self) -> bool

Gets the current link state.

It returns true if the link is up.

pub fn is_autoneg_enabled(&self) -> bool

Gets the current auto-negotiation configuration.

It returns true if auto-negotiation is enabled.

pub fn is_autoneg_completed(&self) -> bool

Gets the current auto-negotiation state.

It returns true if auto-negotiation is completed.

pub fn set_speed(&mut self, speed: u32)

Sets the speed of the PHY.

pub fn set_duplex(&mut self, mode: DuplexMode)

Sets duplex mode.

pub fn read(&mut self, regnum: u16) -> Result<u16>

Reads a given C22 PHY register.

pub fn write(&mut self, regnum: u16, val: u16) -> Result

Writes a given C22 PHY register.

pub fn read_paged(&mut self, page: u16, regnum: u16) -> Result<u16>

Reads a paged register.

pub fn resolve_aneg_linkmode(&mut self)

Resolves the advertisements into PHY settings.

pub fn genphy_soft_reset(&mut self) -> Result

Executes software reset the PHY via BMCR_RESET bit.

pub fn init_hw(&mut self) -> Result

Initializes the PHY.

pub fn start_aneg(&mut self) -> Result

Starts auto-negotiation.

pub fn genphy_resume(&mut self) -> Result

Resumes the PHY via BMCR_PDOWN bit.

pub fn genphy_suspend(&mut self) -> Result

Suspends the PHY via BMCR_PDOWN bit.

pub fn genphy_read_status(&mut self) -> Result<u16>

Checks the link status and updates current link state.

pub fn genphy_update_link(&mut self) -> Result

Updates the link status.

pub fn genphy_read_lpa(&mut self) -> Result

Reads link partner ability.

pub fn genphy_read_abilities(&mut self) -> Result
