const char * tag ()

It is expected that each derived device will implement tag().

uint16_t GetRingSize (uint16_t index)

Get the Ring size for the particular device / backend.

This has to be proxied to a backend method because we can't

simply do config reads to determine the information.

zx_status_t SetRing (uint16_t index, uint16_t count, zx_paddr_t pa_desc, zx_paddr_t pa_avail, zx_paddr_t pa_used)

Set up ring descriptors with the backend.

void RingKick (uint16_t ring_index)

Another method that has to be proxied to the backend due to differences

in how Legacy vs Modern systems are laid out.
