mac80211: restrict advertised HW scan rates
Advertise only user-requested bitrates in a HW scan. Note that the hw_scan API doesn't currently have a way of asking for a specific probe request bitrate, so we might end up using a bitrate that we don't advertise as supported. I'll fix that later. Also add a hexdump printk to hwsim to verify this. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
