Recent versions of linuxthreads use %gs for thread-specific data,
while FreeBSD uses %fs (mostly because WINE uses %gs).

I have not done serious performance testing with this driver. I know
it works, and I want it under CVS control so I can keep tabs on it.
Note that there's no serious mutex stuff in here yet either: I need
to talk more with jhb to figure out the right way to do this. That
said, I don't think there will be any problems.

we need to delete the info from the list as well as zero out the res

Also made a few style(9) changes while I was at it. Don't use if

rather than 0. Don't have useless blocks.

use TAILQ macros. The sk_attach_xmac() routine calls sk_init_xmac()
before doing the transceiver probe, but *before* ether_ifattach()
is called. This causes sk_init_xmac() to call sk_setmulti(), which
tries to do a TAILQ_FOREACH(), which it can't do because ether_ifattach()
hasn't done a TAILQ_INIT() yet. This causes a NULL pointer dereference
and panic in sk_setmulti() at driver load/initialization time.
Fixed by calling ether_ifattach() before the MII probe.
The code in RELENG_4 still uses the old way of enumerating the
multicast list and doesn't have this problem. Yet.
Reduce the verbose memory map setup reports and work with pccardd to
set the common memory map up.
Use enumeration values for CARD_SET_RES_FLAGS.
Use DELAY when spinning waiting for the card to come free instead of a loop.
