o Only complain about detached children that aren't pccard/cardbus.
o Don't NULL out the pccarddev and cbdev devices. detach just
disassociates the device and driver. It doesn't delete the child.
o on driver added, just probe_and_attach the children. If there's
any children attached, wakeup the device add/delete thread.
o wakeup the add/delete thread with the correct cv_signal() rather
than the bogus wakeup(sc). It used to be that we did a tsleep on
sc in this thread, but switched to the more reliable cv stuff a while
ago w/o changing this.
o Remove bogus checks when reallocating memory for the registers. They
weren't needed and turned out to be completely bogus.
This lets me load/unload pccard with a pccard in a slot and have the
child correctly detach/attach. This should help people that have wi
in their kernel, but that kldload cbb and pccard, for example.
we're using an atomic operation to clear the suspend flag
in fxp_start(). Since other architectures may need the
same thing, we want to do it all the time and not only
in the __alpha__ case. However, we don't want to use
atomic operations on 16-bit integers, because those may
not be available on any architecture. We're thus faking
a 32-bit atomic operation here. This patch also deals
with endianness here.
which deals with both endianness and alignment issues.
- Collect low-hanging fruits for endianness safety.
- Use 0xffffffff instead of -1 where appropriate.
endian safe.
- Change some u_int to u_int8_t which make more sense here since
we're really defining bytes. That produces the same code due to
how bitfields work.
- Add the definition of the vlan_drop_en bit (not used yet).
- Add some useful comments.

doubt it will fix the recent breakage that some people are seeing,
but this could have caused problems for sure.

calibration failures and subsequent speed problems with ich chipsets.
Minor calibration comment updates.
This patch is rather big because I had to significantly redesign
the driver to make the busdma conversion possible. Most notably,
hardware and software structures were carefully splitted to get
rid of all the structs overlapping evilness.
Special thanks to phk and Richard Puga <puga@mauibuilt.com> for
providing me with fxp(4) hardware to do this work.
Thanks to marcel for testing this on ia64, and to Fred Clift

Retain the mistake of not updating the devstat API for now.
Spell bioq_disksort() consistently with the remaining bioq_*().
#include <geom/geom_disk.h> where this is more appropriate.
