From a060bbfe4ee95d115e8f9705a66894ac34e2c475 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 27 Apr 2010 11:59:34 +0200 Subject: [PATCH] mac80211: give virtual interface to hw_scan When scanning, it is somewhat important to scan on the correct virtual interface. All drivers that currently implement hw_scan only support a single virtual interface, but that may change and then we'd want to be ready. Signed-off-by: Johannes Berg Signed-off-by: John W.
