RFC for Software / Virtual _DRAFT_ implementation of Bluetooth High Speed
by using wireless driver.

Currently it can be used for testing Bluetooth A2MP protocol.

Please comment is this right way of implementing things like: using virtual
interface to enable AMP. Shall I use module instead? Shall I put files to
mac80211 or use other location? Is name "vamp" OK? Other variants are:
softamp, soft_amp, soft_amp80211, etc.

Main ideas:
 - Use existing wireless infrastructure nl80211, mac80211.
 - Use virtual interface of type NL80211_IFTYPE_VIRTUAL_AMP80211. Then all
drivers supporting virtual interface should work.

After modifying iw it will be enabled by adding new virtual interface.

# iw phy <physical device> interface add vamp type vamp
# iw dev
phy#0
	Interface vamp
		ifindex 6
		type Virtual AMP

# hciconfig
