[PATCH] nl80211: introduce NL80211_SCAN_FLAG_DISCOVERY_MODE

[Vladimir Kondratiev <qca_vkondrat@qti.qualcomm.com>]

for the DMG (60GHz) networks, there is new scan parameter added in the 802.11 spec -
DiscoveryMode.  This parameter defines whether station performing active scan shall
generate special form of DMG beacons. In particular, this flag used in the P2P
discovery.

Introduce flag to support this feature.
