Subject[patch] patch-2.4.0-test11-irda1
From
Linus,

Please apply this patch to your latest 2.4 code. The patch have been
tested by users at the Linux-IrDA mailing-list which confirms that
it fixes the specific problems listed below.

Changes:

o Devfs support with IrCOMM (pmhahn?)

o IrLAN connection failures with DHCP (me)

o NSC FIR dongle fixes (Pontus Fuchs)

o Fixes IrLAP discovery problems with some devices (me)

o Updates to some doc files (me)

To use the IrDA protocols within Linux you will need to get a suitable copy
of the IrDA Utilities. More detailed information about these and associated
-programs can be found on http://www.cs.uit.no/linux-irda/
+programs can be found on http://irda.sourceforge.net/

For more information about how to use the IrDA protocol stack, see the
