Detailed Description

Queue resources.

Written by the device to indicate the indices of the chosen event counter and descriptor doorbell register.

This appears to be a largely pointless data structure: the relevant information is static for the lifetime of the queue and could trivially have been returned in the response for the "create transmit/receive queue" command, instead of requiring yet another page-aligned coherent DMA buffer allocation.
