Hash Table Index. If the frame was accepted as a result of
a hash table match, these bits contain the hash table
index, otherwise they are written as zero. If the frame was
received as a result of Promiscuous Accept, this field will
be zero. If the frame was accepted as a result of an
Individual Address Match then the field indicates which
address was matched, as follows:
000001 - Frame matched Individual Address 0
000010 - Frame matched Individual Address 1
000100 - Frame matched Individual Address 2
001000 - Frame matched Individual Address 3
Receive Frame Processed. The Receive Frame
Processed bit is always written as a 1 by the MAC when
the status is ready and it may be used by the Host to mark
its progress through the status queue.
Buffer Index. This field contains the buffer index field from
the descriptor table for the data buffer associated with this
status entry.
Frame Length. The frame length field contains the total
number of bytes transferred for this frame. For an
intermediate status (not end of frame) this is the total
number of bytes transferred up through the current data
buffer.
