A bit of a messy monster.
A bit of a messy monster.

Simple stuff
------------

	Split _download up so that the MIB settings are in their own functions.

	Made "tx completed but status is ..." a recoverable error

	Cut down verbosity of "unloaded" messages

	Moved ccs_free and com_runq from intr_ccs to ecf_done and runq_done
	to avoid embarasing mistakes and waits.

	Merged runq_add and runq_arr into one and called it runq_add

	Made RAY_COM_DUMP a real debug called RAY_DCOM

	Consistnet debugging around tsleeps.

	Use bus_activate_resource for attr/cm mapping, and set the flags
	correctly in the allocation routines (needs more hacks to
	sys/pccard/pcic.c)

	com_malloc is now seperated from the comq initialization. This was
	done whilst trying to set automatic variables for the comqs.

Harder Stuff
------------

	As part of the IFF_RUNNING fixes, remove the panic in runq if we are
	not running.

	Change, again, runq_add. This time we don't do any cleaning up
	if there were errors. This is so that callers get the chance
	to re-try (not that I ever see it being used).

	In runq_add, only sleep when there is something to sleep on!

	ioctl locking routines, stolen from awi.c but not used


Hardest Stuff
-------------

	Dealing with serialing ioctls correctly means that we must QUEUE
	changes to IFF_RUNNING and check it in the QUEUED commands, not
	in the user commands. Whilst simple to state, it took a few
	hours of head scratching to get it right. The realisation was that
	I only have to guarantee that sub-commands from a single process
	are serialised and "atomic", and that they check the status of the
	interface flags when invoked and not when they are queued.

	Another way of looking at it, is that the driver's state is stored
	in the runq and the IFF_RUNNING flag. These must be changed together.

	What this means practically, is that IFF_RUNNING is set after
	we have started/joined/associated with a network. And it is
	cleared by ray_stop via the runq so that unfinsished commands are
	not distrupted.

	I still have to fix up promisc, upp/repparams and mcast.

	Oh yeah, stop is essentially a noop in that it only
	changes IFF_RUNNING
