If you're more comfortable just sending packets to the device, doing
it in user space would be much better.

It would also make it possible to work on OS X, because there's no
IRDA stack at all there.

So a user space stack would likely be simpler, easier to test, and
actually technically superior.

The "do IRDA in kernel space" made sense back in the bad old days when
IRDA was a real protocol used for transferring files and stuff, and
was supposed to be generic.

It never worked very well even back then, but at least it made sense
to have IRDA as a networking stack.

Today, the _only_ user I'm aware of is old dive computers. It doesn't
make sense as a networking stack any more.
