Actually, I'm not 100% happy with the IrDA situation. I would
not mind someone exporting more events to RtNetlink, very similar to
the functionality/events I already provide in the IrNET control
channel (discovery/expiry/link blocked/...).
Note that if you are only interested in IrNET, then the IrNET
control channel gives you everything you need, and you don't really
need to use RtNetlink. Personally, I think the future of IrDA is
IrNET, so that's why I don't bother with the rest.
In any case, send me a link to you applet, I'll add that on my
web page.

Check this thread :

Basically, you need to check the code in hcid.c (in utils) to
know how to collect this events. I've coded this and it works
perfect. Yeah, it's another socket to manage.
