mac80211: Support dynamic AP mode channel width changes
Implement the new cfg80211 capability to enable mac80211-based drivers to support for dynamic channel bandwidth changes (e.g., HT 20/40 MHz changes). Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
