Counts the number of frames that have been flushed from the receive packet buffer
memory due to one of the following reasons:
- When partial store and forward mode is
enabled and a packet is received while there is no system bus resource
- When partial store and forward mode is
enabled and a system bus error is encountered while writing the packet data to
system memory.
- When automatic discard of received packed during lack of resource is enabled (bit
24 of the DMA Configuration register) and a packet is received while there is no
system bus resource.
- When a software flush of a packet
from the head of the packet buffer queue (bit 18 of the Network Control register)
is performed and the DMA is not currently busy.
