[net.unix-wizards] 4.3BSD Interlan driver implementation

--[---]--

I recently noticed that although the Interlan NI1010 Ethernet controller
has a large onboard receive buffer and a queue for sixteen pointers
to Unibus buffers for DMA ... the 4.3BSD driver (if_il.c) uses only
one Unibus buffer for packet reception.  I'm interested in increasing
the reception performance of the driver, and I wondered if anyone 
had considered extending the code to use more than one Unibus buffer.
I'd be interested in any information, from actual implementation
to mere musings.  If I receive sufficient response, I'll summarize.
