- Don't bother setting OACTIVE when the descriptors are all full
or there's a vr_encap failure, it doesn't help anything.
- Correctly roll back on the descriptor list after a failure
so as not to corrupt the list.
- Add a missing VR_UNLOCK().
Without these changes, vr_encap failure (which is assured during
a low mbuf situation) would result in the card locking until
the watchdog could fire.

Boost sample rate to 1.25 MSPS since that allows us to use a 5Mhz
(/4) or 10Mhz (/8) external clock.
Make the interrupt both MPSAFE and FAST, at 610 interrupts a second,
and a max time to service of 5 msec, we brake for nobody.
Use kernel thread to accumulate into the 25 possible wave signals.
Use #ifdef _KERNEL to let .c file double as .h file defining the ioctls.
of the entries have a description, we'll use that to override the
description that the pccard layer generates for us.
This saves about 930 bytes in the module, so I feel it won't hurt the
crowded boot disks....

of asserting that an mbuf has a packet header. Use it instead of hand-
rolled versions wherever applicable.

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.

other allocations/initializations have been successful. I kinda
doubt it will fix the recent breakage that some people are seeing,
but this could have caused problems for sure.
