o add back rx monitor support
o make WI_RID_SCAN_RES DTRT
o fix a bug handling zero-length RID requests (used by dstumbler to set
a zero-length SSID)
o make RID_SCAN_REQ DTRT
o add back WI_RID_OWN_SSID
o fix wi_scan_ap to take a channel mask and txrate (for prism cards)
These changes fix dstumbler -o (monitor mode). A minor change to dstumbler
is needed to get normal AP scanning mode to work right; this is preferred to
modifying the driver.

than once. This appears to work around the hanging issues, at the
expense of warnings about bad RID allocations. I'm not sure this is a
permanant workaround, but does appear to help in the tests that I've
done here.
that one cannot generally hold a lock and call bus_teardown_intr.
This is race free with wi_intr because bus_teardown_intr won't allow
wi_intr to be called after it returns.
# jeff hsu points out that there might be a race between this unlock
# and wi_start. While that may be true also, it won't impact this commit.

firmware 1.50.12, but 2.20.1 and 3.10.4 work. The 1.50.12 card gets
past doing dhclient, but hangs on transmit a little after the ip
address is set. The 1.50.12 card has always been 'cranky' and Bill
Paul's tearing it apart at FreeBSD '99 hasn't helped.
sc_reset and sc_enable are subtlely different things. sc_reset means
exactly "WI_CMD_INI has happened." sc_enabled means "WI_CMD_ENABLE
has been sent to the card without a WI_CMD_DISABLE following." This
is a little different than what they mean on NetBSD (where both of
these concepts are comingled). NetBSD will try to only enable symbol
cards once, while FreeBSD only sends the WI_CMD_INI once.
Also, only try once to reset the card on a symbol.
This makes the lucent cards no worse than before, but apparently not
much better either. I got fewer hangs in my testing than I have in
the past, but I don't know if it is statistically significant or not.

Put what I think are the correct TX RATE translation tables
in place for LUCENT firmware. This is based on the 4.x driver.
Maybe it should be table driven?
ifconfig wi0 media DS/11Mbps still fails, but it fails before
we even get to the txrate stuff, so other things are wrong.

Default ic_fixed_rate to -1. This is the same thing as autoselect.
There really should be a #define for this...
one tx buffer for these cards. The old driver only used one. We use
1 for symbol, and 3 for prism cards.
o Don't do the maximum loops thing in the ISR. In fact, revert to the
old interrupt handler. Lucent cards don't seem to work too well if
you don't disable/enable interrupts from the card in the ISR.
Between these two changes, Lucent cards suck less. They work in
autoselect mode only. And seem to get 1Mbps or 2Mbps only. Setting a
specific media speed doesn't work, and I've had a few issues even with
these patches. They turn a former brick into a nearly useful card.
These patches work on the prism 2 and 2.5 PC Card cards that I have.
I've not tested this on PCI cards. I suspect, but couldn't find
proof, that they were the reason that the ISR was changed so radically
from its FreeBSD roots in NetBSD. We might need to have a variant ISR
if so.
code both seem to call wi_start (directly or via the if_start pointer)
without checking to see if OACTIVE is 0. In addition, I think that
with the use of 3 transmit buffers this routine can be called with
OACTIVE set, but I might be mistaken about that (and it doesn't
matter).

Also use a few constants in place of magic numbers in one place.

to get a relatively pure baseline. This doesn't seem to break what
works now.
