From 4d2a5d0ecd3d5350957ed8afc4cee2dbc606c7e2 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sat, 23 Jul 2011 10:24:46 -0700 Subject: [PATCH] iwlagn: move context init after firmware loading The availability of contexts depends on the firmware capabilities. Currently only the presence of the second context depends on it, but soon P2P support will also be different. Move the context initialisation code to the firmware-dependent setup before registering with mac80211 to make it easier to handle.
