From 2056cd84dde73cc337aecef4745e4a4b83fff89b Mon Sep 17 00:00:00 2001
From: Aloka Dixit <quic_alokad@quicinc.com>

Subject: [PATCH 3/7] hostapd: add driver capability

Extended feature flag NL80211_EXT_FEATURE_DEVICE_BW indicates that
the driver supports different parameters for the device bandwidth
compared to the operating bandwidth. Store the capability.
Modify nl80211_put_freq_params() include a pointer to the driver
context so that the capability can be verified when such parameters
are passed. Driver capabilities flags 
WPA_DRIVER_DEVICE_PARAMS_SUPPORTED is set to adevertise this feature 
to hostapd
