workalike chips (Macronix 98713A/98715 and PNIC II). Timing is somewhat
critical: you need to bring the link as soon as possible after NWAY

we poll every 10th of a second until NWAY completes (at which point
we return to the 1 second interval again to keep an eye on the link

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
