I assume that 20-40 coex is a separate feature. Drivers not using SME in wpa_supplicant should also be able to use it. Hence SME capability check is removed in below patch. The patch has been tested with mwifiex driver.

Please let me know if I am missing something.

From: Amitkumar Karwar <akarwar at marvell.com>

Some nl80211 based non-SME drivers (ex. mwifiex) are capable of
receiving management frames prepared in wpa_supplicant. Hence the
check for WPA_DRIVER_FLAGS_SME flag is removed so that they can
use 20/40 coex feature.
