From 4fa004373133ece3d9b1c0a7e243b0e53760b165 Mon Sep 17 00:00:00 2001 From: Sujith Date: Mon, 1 Mar 2010 14:42:57 +0530 Subject: mac80211: Fix HT rate control configuration Handling HT configuration changes involved setting the channel with the new HT parameters and then issuing a rate_update() notification to the driver. This behavior changed after the off-channel changes. Now, the channel is not updated with the new HT params in enable_ht() - instead, it is now done when the scan work terminates. This results in the driver depending on stale information, defaulting to non-HT mode always. Fix this by passing the new channel type to the driver.
