From a591697730a3c416cd384bc199eb5dde622c4c78 Mon Sep 17 00:00:00 2001 From: Gregory Greenman Date: Tue, 10 Jan 2012 19:22:56 +0200 Subject: [PATCH] iwlwifi: Connect IDI transport to driver. This patch connects IDI transport to driver. It does so by using a number of ifdefs at this stage. IDI is a new transport that is under development.
