From fc8fd3400b716615933a47be453839d190b235bd Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Sun, 25 Jun 2006 21:32:21 -0500 Subject: [PATCH] [PATCH] Convert bcm43xx-softmac to use the ieee80211_is_valid_channel routine The current version of bcm43xx-softmac uses local routines to check if a channel is valid. As noted in the comments, these routines do not take any regulatory information into account. This patch converts the code to use the equivalent routine in ieee80211, which is being converted to know about regulatory information. Signed-Off-By: Larry Finger Signed-off-by: John W.
