o Attempt to disable the slot when we detect that there are problems with
it in our ISR. This should make polling mode work better for more cards,
but more work may be needed. This "disabling" sets the card interrupt
register to 0. This worked for me for lots of tests in polling mode.
o Now that I've found datasheets, fix a boatload of magic numbers in the
source to make it easier to understand.
o Use a table of names rather than a big case statement.
o Cull a few of the "unused" controller types that we map to other times
that were a vestiage of PAO code that we never merged in the same way.
o Enforce legal IRQs. You are no longer allowed to try to use IRQs that
will fail on all known ISA/PCI <-> PCMCIA bridges. The bridges do not
have pins for these illegal interrupts, and all of them are listed as
reserved and/or illegeal in the datasheets depending on which one you
look at.
o Add comments about how IBM-AT based computers and NEC PC-98 based computers
map these interrupts and which ones are valid.
o Always clear the bit that steers the management interrupt either to the
value listed in the PCIC_STAT_INT register. I've seen this bit get set
on suspend/resume and after windows boot, and it does't hurt to clear it.
NOTE: this might mean we can share this interrupt in the future.

deprecated in favor of FFS over md. Note also that UFS_EXTATTR_AUTOSTART
doesn't make much sense on MFS unless the MFSROOT is compiled in, so
manual configuration is generally required.

Correct code that traverses the phase table. A much too quick
push to staticize this structure resulted in non-functional
lookup code. This corrects the printing of the phase where
a timeout occurred.

Use FIFOQWDEMP as the name for bit 5 of DFSTATUS just like

aic7xxx.seq:
Refine the 2.1 PCI retry bug workaround for certain, non-ULTRA2,
controllers. When the DMA of an SCB completes, it can take
some time for HDONE to come true after MREQPEN (PCI memory request
pending) falls. If HDONE never comes true, we are in the hung
state and must manually drain the FIFO. We used to test HDONE for
3 clock cycles to detect this condition. This works on all of the
hardware I can personally test. Some controllers were reported
to take 4 clock cycles, so the last version of this code waited
4 clock cycles. This still didn't work for everyone. To fix this,
I've adjusted the work around so that even if the hardware hasn't
hung, but we run the work-around code, the result is a long winded
way to complete the transfer, rather than a hang.

reflects the fact that our EA support is implemented entirely at the
UFS layer (modulo FFS start/stop/autostart hooks for mount and unmount
events). This also better reflects the fact that [shortly] MFS will also
support EAs, as well as possibly IFS.
o Consumers of the EA support in FFS are reminded that as a result, they
must change kernel config files to reflect the new option names.

using it. Not checking this may have caused the wrong IP address to be
used when processing certain IP options (see example below). This also
caused the wrong route to be passed to ip_output() when forwarding, but
fortunately ip_output() is smart enough to detect this.
This example demonstrates the wrong behavior of the Record Route option
observed with this bug. Host ``freebsd'' is acting as the gateway for
the ``sysv''.
1. On the gateway, we add the route to the destination. The new route
will use the primary address of the loopback interface, 127.0.0.1:
: freebsd# route add 10.0.0.66 -iface lo0 -reject
: add host 10.0.0.66: gateway lo0
2. From the client, we ping the destination. We see the correct replies.
Please note that this also causes the relevant route on the ``freebsd''
gateway to be cached in ipforward_rt variable:
: sysv# ping -snv 10.0.0.66
: PING 10.0.0.66: 56 data bytes
: ICMP Host Unreachable from gateway 192.168.0.115
: ICMP Host Unreachable from gateway 192.168.0.115
: ICMP Host Unreachable from gateway 192.168.0.115
:
: ----10.0.0.66 PING Statistics----
: 3 packets transmitted, 0 packets received, 100% packet loss
3. On the gateway, we delete the route to the destination, thus making
the destination reachable through the `default' route:
: freebsd# route delete 10.0.0.66
: delete host 10.0.0.66
4. From the client, we ping destination again, now with the RR option
turned on. The surprise here is the 127.0.0.1 in the first reply.
This is caused by the bug in ip_rtaddr() not checking the cached
route is still up befor use. The debug code also shows that the
wrong (down) route is further passed to ip_output(). The latter
detects that the route is down, and replaces the bogus route with
the valid one, so we see the correct replies (192.168.0.115) on
further probes:

- Make sure that m_mballoc() really doesn't allow over nmbufs mbufs to
be allocated from mb_map. In the case where nmbufs-reserved space is not
an exact multiple of PAGE_SIZE (which it should be, but anyway...), we
hold nmbufs as an absolute maximum which need not ever be reached.
- Clean up m_clalloc(); make it more consistent in the sense that the first
argument `ncl' really means "the number of clusters ensured to be allocated"
and not "the number of pages worth of clusters to be allocated," as was
previously the case. This also makes it consistent with m_mballoc() as well
as the comment that preceeds it.
