Expand description

Unified network device interface.

Kernel-resident drivers wrap their hardware-specific struct in a SpinLock and implement this trait with interior mutability. Future silo-hosted drivers expose the same interface via IPC.

Required Methods§

Source

fn link_up(&self) -> bool

Provided Methods§

Source

fn handle_interrupt(&self)

Source

fn poll(&self)

Periodic housekeeping called from the timer path (or interrupt context). Default is a no-op; drivers that need a watchdog or buffer-reclamation cycle override this.
