config file instead of hard-coding it in the driver. No functional
differences.
This is based on the code Richard Wiwatowski <rjwiwat@adelaide.on.net>
sent to the mailing list.
- Prepend PSM_ to some defines to avoid any possible name-space problems
- Use some already defined constants instead of magic #'s where appropriate.
[ No functional changes (yet) ]
the destination represents. For IP:
- Iff it is a host route, RTF_LOCAL and RTF_BROADCAST indicate local
(belongs to this host) and broadcast addresses, respectively.
- For all routes, RTF_MULTICAST is set if the destination is multicast.
The RTF_BROADCAST flag is used by ip_output() to eliminate a call to
in_broadcast() in a common case; this gives about 1% in our packet-generation
experiments. All three flags might be used (although they aren't now)
to determine whether a packet can be forwarded; a given host route can
represent a forwardable address if:
(rt->rt_flags & (RTF_HOST | RTF_LOCAL | RTF_BROADCAST | RTF_MULTICAST))
== RTF_HOST
Obviously, one still has to do all the work if a host route is not present,
but this code allows one to cache the results of such a lookup if rtalloc1()
is called without masking RTF_PRCLONING.
it empties all of the 256 byte incoming fifo, as it can spend more time
processing one port than intended, especially if data is streaming in
at 115.2K. The port fifo will be emptied and dumped into the tty system
and left until next time. I've been running this for quite some time on
one of my systems here.
Also, if the tty layer is blocked or full it lets the hardware assert the
flow control rather than loosing the data.
Compile for FreeBSD-2.2

-current's VM include files have changed lately, this needed to be updated.
Use correct major number.
This is now two seperate drivers that support (I think) all of Stallions's
range, including the high performance intelligent cards, and their older
cards.

This is a multiple import of all revisions available to build up
a history.
This driver supports only some of the Stallion range, in particular, not
the highly intelligent cards. That comes in shortly.

Macroize locore.s' page table setup even more, now it's almost readable.
Rename PG_U to PG_A (so that I can...)
Rename PG_u to PG_U. "PG_u" was just too ugly...
Remove some unused vars in pmap.c
Remove PG_KR and PG_KW
Remove SSIZE
Remove SINCR
Remove BTOPKERNBASE
This concludes my spring cleaning, modulus any bug fixes for messes I
have made on the way.
(Funny to be back here in pmap.c, that's where my first significant
contribution to 386BSD was... :-)
