Ethernet PHY driver.

Required Methods

fn init<M: MdioBus>( &mut self, mdio: &mut M, max_speed: Speed, ) -> Result<(), PhyError>

One-time hardware initialization.

Must reset the PHY, configure auto-negotiation, and wait until the hardware is ready to respond to further MDIO transactions.

max_speed is the fastest speed the wired MAC interface can carry (100 Mbps for MII/RMII, 1000 Mbps for RGMII). Faster abilities must not be advertised, or the link partner may settle on a speed the MAC cannot drive.

fn poll_link<M: MdioBus>( &mut self, mdio: &mut M, _cx: Option<&mut Context<'_>>, ) -> LinkState

Polls the current link state.

Returns LinkState with up == true once the link partner is detected.

In async mode the context must be used to schedule the next poll: register a waker for a PHY interrupt or a timer, or wake immediately. An implementation that does neither will never be polled again, so drivers without an interrupt source wake immediately, which busy-polls. Wrap them to rate-limit the polling if a timer is available.

fn address(&self) -> u8

Returns the Clause 22 PHY address on the MDIO bus.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
