[bit17:0] count: Receive resource errors
An 18-bit register counting the number of frames that were successfully received by the Ethernet MAC
(correct address matched frame and adequate slot time) but could not be copied to memory because
no receive buffer was available. This occurs when the Ethernet MAC reads a buffer descriptor with its
ownership (or used) bit set.
