This driver is strange -- it never sets IFF_OACTIVE, so all
transmissions always cause a call to fxp_start. However, if the
link gets stuck, there was nothing to reset it, so there was still
a possibility of lockups.

the device stalling on transmissions if some link event prevents
transmission.
There are other drivers which have the same problem and need to be
fixed in the same way.

I don't know if people think that these debugging macros are worth keeping

queue stuffups in the (rather complicated) run queue code exists.

The case in cpu_switch() where there isn't a higher priority thread
(choosethread() == curthread) uses r4 as the PCB context pointer. However, the
use of r4 after the label L2 is incorrect, since it was probably trashed by
the call to choosethread, and in any case was set up to curthread at the start
of the routine.
This condition will occur when an interrupt thread schedules a netisr, which
is a lower priority thread.
Another (probably unnecessary) difference is that I was paranoid about
register trashing, so I decided to save r2 and r13 as well.
