tls ab54d7e94f Add support for jumbo (9K) frames. Add support for larger receive 
descriptor sizes if larger mbuf clusters are in use -- currently
commented out because, for some reason, transmit doesn't work at
all with large mbuf cluster sizes.

Note that using actual 9K frames is a _lot_ less efficient than
using frames that are a little smaller than 8K so that they fit
in one or two pages (instead of two or three) and avoid the extra
chained descriptor with only 1K of data in it, too.  TCP will
segment things just fine for an 8K total packet size, just as it
does for 1500-byte packets.

On my system, using "mtu 8000" with ifconfig, I get an almost 50%
performance boost for TCP (930Mbit/sec instead of 660Mbit/sec) over
1500-byte frames.  "mtu 9000" yields only 770Mbit/sec.

README 

$NetBSD: README,v 1.3 1998/08/15 03:02:46 mycroft Exp $

This directory contains files which are used during PCI configuration
and PCI device drivers.  Eventually, most of the device drivers and
some of the configuration support should become machine-independent
and be moved to a more general location.

The configuration support was implemented according to the `PCI Local
Bus Specification, Production Version, Revision 2.0' dated April 30,
1993.  Section numbers referred to in the code may be specific to that
edition of the specification.

Some attempt has been made to insure that the code works on rogue
machines where the BIOS doesn't do its job, but in general I can't
guarantee that.
