From 411725280bd0058ebb83c0e32133b7a94902c3a6 Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Mon, 2 Jul 2007 22:55:31 -0700 Subject: [PATCH] [IrDA]: Monitor mode. Through the IrDA netlink set mode command, we switch to IrDA monitor mode, where one IrLAP instance receives all the packets on the media, without ever responding to them.
