Enum MacError 

pub enum MacError {
    Phy(PhyError),
    ResetTimeout,
    StopTimeout,
    DmaBufferAboveCacheBoundary {
        addr: u32,
    },
}

Errors surfaced by the top-level MAC/device lifecycle.

Variants

Phy(PhyError)

PHY initialization or negotiation failed.

ResetTimeout

DMA reset did not complete in time.

StopTimeout

DMA stop sequence did not quiesce in time.

DmaBufferAboveCacheBoundary

One of the descriptor or buffer arrays handed to the constructor lives at or above the L2-cache backing region (0x4FF80000). Bus masters cannot read or write that range, so any DMA transfer would silently fail. Place StaticDmaResources under #[link_section = ".dma_bss"] (the linker script’s RAM_DMA region keeps it below the cache boundary).

Fields

addr: u32

Address that fell outside the DMA-safe range.

Trait Implementations

impl Clone for MacError

fn clone(&self) -> MacError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MacError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MacError

fn eq(&self, other: &MacError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
