HD64570 chip. Both the 2 and 4 port cards is supported and auto detected.
Line speeds of up to 2Mbps is possible. At this speed about 85% of the
bandwidth is usable with 486DX processors.
The standard FreeBSD sppp code is used for the link level layer. The
default protocol used is PPP. The Cisco HDLC protocol can be used by
adding "link2" to the ifconfig line in /etc/sysconfig or where ever
ifconfig is run.
At the moment only the V.35 and X.21 interfaces is supported. The others
may need tweaks to the clock selection code.

is acknowledged, it should go to the lcp ack sent state.
Don't reply on lcp echo requests when not in the lcp opened state.
If the interface is set to CISCO mode, it should still be marked
running when ifconfiged.
Fixed a few indentations that had gone wrong somewhere.

turn off the read data block timeouts. This was inspired by the same fix
in sendmail-8.7, but the code in this area is somewhat different. (8.7
is much more sensible). This will stop the infamous
"timeout waiting for input during message body read" on long running jobs,
eg: /etc/daily | mail root.
bit set. I broke stat_imask in Dec 1994 and update_intr_masks() has
copied the breakage to intr_mask[8] since Mar 1995. This can cause
the RTC to stop interrupting in rare cases (under loads heavy enough
for a new RTC interrupt to occur at a critical time just before Xintr8
finishes handling the previous one) and may have caused worse problems.
Convert the remaining sysctl stuff to the new way of doing things.
the devconf stuff is the reason for the large number of files.
Cleaned up some compiler warnings while I were there.
replacing them with TAILQ's as appropriate. The SCSI code is the
first to be changed -- until the changes are complete, both b_act and
b_actf will be in the buf structure. b_actf will eventually be removed.
1) Make cluster buffer list be a non-malloced chain. This eliminates
yet another 'evil' M_WAITOK and generally cleans up the code.
2) Fix write clustering for ext2fs. It was just broken. Also, ffs
clustering had an efficiency problem that more bawrites were happening
than should have been.
3) Make changes to buf.h to support the above, plus remove b_pfcent
at the request of David Greenman.
Note that the reallocblocks code is disabled pending rewrite for
the cluster buffer list changes.

that if you do an rup on a machine that's been running longer than a year,
you get the wrong day count. Now we factor in 365 * (curtime.tm_year -
boottime.tm_year) to get the correct value. (I noticed this while running
rup on a SunOS machine I have that's been up 525 days. My FreeBSD
machines all said it had only been up for 160 (525-365) days. :)
