+6LoWPAN Linux implementation
+============================
+
+The IEEE 802.15.4 standard specifies an MTU of 128 bytes, yielding about 80
+octets of actual MAC payload once security is turned on, on a wireless link
+with a link throughput of 250 kbps or less. The 6LoWPAN adaptation format
+[RFC4944] was specified to carry IPv6 datagrams over such constrained links,
+taking into account limited bandwidth, memory, or energy resources that are
+expected in applications such as wireless Sensor Networks. [RFC4944] defines
+a Mesh Addressing header to support sub-IP forwarding, a Fragmentation header
+to support the IPv6 minimum MTU requirement [RFC2460], and stateless header
+compression for IPv6 datagrams (LOWPAN_HC1 and LOWPAN_HC2) to reduce the
+relatively large IPv6 and UDP headers down to (in the best case) several bytes.
+
+In Semptember 2011 the standard update was published - [RFC6282].
+It deprecates HC1 and HC2 compression and defines IPHC encoding format which is
+used in this Linux implementation.
+
+All the code related to 6lowpan you may find in files: net/ieee802154/6lowpan.*
+
+To setup 6lowpan interface you need (busybox release > 1.17.0):
+1. Add IEEE802.15.4 interface and initialize PANid;
+2. Add 6lowpan interface by command like:
+ # ip link add link wpan0 name lowpan0 type lowpan
+3. Set MAC (if needs):
+ # ip link set lowpan0 address de:ad:be:ef:ca:fe:ba:be
+4. Bring up 'lowpan0' interface
when using large numbers of interfaces and when communicating
with large numbers of directly-connected peers.
+neigh/default/unres_qlen_bytes - INTEGER
+ The maximum number of bytes which may be used by packets
+ queued for each unresolved address by other network layers.
+ (added in linux 3.3)
+
+neigh/default/unres_qlen - INTEGER
+ The maximum number of packets which may be queued for each
+ unresolved address by other network layers.
+ (deprecated in linux 3.3) : use unres_qlen_bytes instead.
+
mtu_expires - INTEGER
Time, in seconds, that cached PMTU information is kept.

* @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
* @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame.
*
+ * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
+ * (or GO) interface (i.e. hostapd) to ask for unexpected frames to
+ * implement sending deauth to stations that send unexpected class 3
+ * frames. Also used as the event sent by the kernel when such a frame
+ * is received.
+ * For the event, the %NL80211_ATTR_MAC attribute carries the TA and
+ * other attributes like the interface index are present.
+ * If used as the command it must have an interface index and you can
+ * only unsubscribe from the event by closing the socket. Subscription
+ * is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
+ *
+ * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
+ * associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
+ * and wasn't already in a 4-addr VLAN. The event will be sent similarly
+ * to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
+ *
+ * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
+ * by sending a null data frame to it and reporting when the frame is
+ * acknowleged. This is used to allow timing out inactive clients. Uses
+ * %NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
+ * direct reply with an %NL80211_ATTR_COOKIE that is later used to match
+ * up the event with the request. The event includes the same data and
+ * has %NL80211_ATTR_ACK set if the frame was ACKed.
+ *
+ * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
+ * other BSSes when any interfaces are in AP mode. This helps implement
+ * OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
+ * messages. Note that per PHY only one application may register.
