Struct QemuShmDriver 

pub struct QemuShmDriver { /* private fields */ }

Driver state — owns a single RX frame buffer to keep storage small. The C side serialises ring access; a single in-flight frame at a time is fine for the SHM transport’s throughput envelope.

Implementations

impl QemuShmDriver

pub fn new(mac: [u8; 6]) -> Self

Construct the driver and announce ourselves to the host bridge. Safe to call once; subsequent calls reset ring positions.
