	"Inappropriate ioctl for device(25)" is ENOTTY. The code in
IrNET never generates this error, it is only generated in
ppp_generic. It looks like the PPP code got seriously confused and
generated the ioctl on the wrong device.
	Note also that channel registration can't fail, unless you get
out of memory or for non-root, so I doubt this is happening.
	You can enable IrNET debugging code in irnet.h, but in this
case I don't think it will tell much.
