[$] A tale of two troublesome drivers

The kernel project merges dozens of drivers with every development cycle,
and almost every one of those drivers is entirely uncontroversial.
Occasionally, though, a driver submission raises wider questions, leading
to lengthy discussion and, perhaps, opposition. That is currently the case
with two separate drivers, both with ties to the networking subsystem. One
of them is hung up on questions of whether (and how) all device
functionality should be made available to user space, while the other has
run into turbulence because it drives a device that is unobtainable outside
of a single company.
