Suppress the peer notifications while a ring keeps delivering work, batch the receive completions into one kick per burst and drop the redundant txdone signal from the transmit path. Validate the peer controlled frame lengths, accept descriptor chains on both lanes, keep every ring access on the upper half's work thread so the interrupt context callbacks stay lock free, and prefer the MAC from the configuration space, falling back to the Kconfig address or a random one.

Framework for implementing the DEVICE side of virtio links

(the peer's driver uses us as the device, e.g. a remoteproc

master like Linux). rptun registers device-role vdevs from the

|
resource table through this bus; without it such vdevs are

rejected with -ENODEV.
