Draft Software/Virtual AMP80211

From: Andrei Emeltchenko <andrei.emeltchenko-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

RFC for Software / Virtual _DRAFT_ implementation of Bluetooth High Speed
by using wireless driver. Currently it can be used for testing Bluetooth
A2MP protocol.

Changes:
	RFCv2: Process basic HCI commands and basic data traffic; added skeleton
	for Netlink comms, took comments from reviewers.
	RFCv1: Initial release.

TODO:
	Change names from vamp to <softamp|bt_softamp|etc>

Main ideas:
 - Use existing wireless infrastructure nl80211, mac80211.
 - Use virtual interface of type NL80211_IFTYPE_BLUETOOTH_AMP. 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

	TX bytes:0 acl:0 sco:0 commands:0 errors:0
