This adds support for EtherExpress/16 cards with 16k of RAM, and in the
process adds general support for PIO mode on these cards. This entails
changing the way the i82586 driver handles bus barriers, since it doesn't
allow for strange cases like this.
This has been tested on the i386 port with the 'ix' driver in both
16KB (which was the source of the problem) and 32KB modes, as well
as with the 'ef' driver. I've tested it (briefly) with 'ei' on arm26
as well. In theory, drivers other than 'ix' should follow precisely the
same code paths as before.
the number of partitions is > OLDMAXPARTITIONS. This is better
than silently truncating the label (don't want to silently throw
away partitions when using an old disklabel binary on a label with
> 8 partitions). From Enami Tsugutomo.
This is the kernel part (userland to follow soon) of the latest (and
very probably last) release (version 0.96) of ISDN4BSD. ISDN4BSD has a
homepage at http://www.freebsd-support.de/i4b/.
It gives the user various ways to use the isdn connection: raw data (via
the i4brbch "raw b-channel" device), ppp (via the isp "isdn PPP" device),
voice/answering machine (the i4btel "telephone" device) and ip over isdn
(the ipr device, "IP over raw ISDN").
Supported are a bunch of common and older cards, more to be added soon
after some cleanup. Currently only the european E-DSS1 variant of the
ISDN D channel protocol is supported.

(This eliminates 1/3 of the instances of PHOLD()/PRELE() in the kernel code.)

register for a port under high load. The effect is that the port is wedged
waiting for an interrupt that will never come.
Add a callout-based watchdog which periodically (hz/10) scan trough the ports
for missed interrupts.
Problem also noted by Chris Jones, and this fix also helped him.
a) use stream methods when transferring data via the MEMPORT into/out of
the chips buffer memory
b) use htole16/le16toh when interpreting 16bit values in the chips memory
Both where NOPs on i386 machines, which is why this worked before on the
test machine(s), but would break when on a big-endian machine.
it, before starting the command to install the multicast list.
(We did it right for writing data packets, but failed here.)
Without this, the last multicast address installed won't be made active.
