From fcab189027cdd68df7f97474d1419aaa4a82130c Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Thu, 22 Nov 2012 18:06:18 +0200 Subject: [PATCH] wlcore: update channel_switch/stop_channel_switch commands Some fields were added to the channel_switch and stop_channel_switch commands. Unfortunately, the new 18xx channel_switch struct is not backward compatible with the 12xx channel switch struct. Add a new channel_switch op to wlcore, and update the driver accordingly.
