[PATCH] nl80211: introduce NL80211_SCAN_FLAG_DISCOVERY_MODE

[Vladimir Kondratiev]

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.

Max 72 chars per line please.

"scan to use" - did you mean "scan using"?

Also what about a feature flag? Though I suppose this should be
supported by all 60GHz devices (and only those)?

Ok, so you can't even get your own email address right - I'll ignore you
for a few weeks until you maybe get it right.
