Swtich sockets to connected when talking to a specific AC. Use
unconnected UDP sockets only during DISCOVERY.
In JOIN, we need send our local address. The old, routing table
based local address discovery is broken for many reasons (VRF,
policy routing, ...). With a connected socket, we can the same
information with a simple getsockname.
During DISCOVERY we are talking to all potential AC's at once.
So using an unconnected socket makes still sense.
Hard coding basic rates is wrong. Each Wifi types does expect
some default basic rates. However those rates are not set in
stone and the AC is permited to set then to whatever it deems
ok. This might prevent client from connecting, but it still is
the AC decission to do so.
This is first step towards a more flexible basic rate handling.
RFC 5416 does require IEEE 802.11 WTP Radio Information for
Discovery and Join Response Messages in Chapter 5. However
Chapter 6.25 indicates that this IE should only be included
in the request messages.
The director has the opportunity to change the configuration of AC in join
connection. The virtual interfaces which encapsulate the wifi stations is
managed dynamically by the Director.
The AC must request authorization from Director for associate a station.
Complete the IEEE802.11 Station Association with interation of AC in LocalMAC mode.
After the IEEE802.11 Authorization / Association is complete, the AC can now
authorize the WTP to accept data station packets with Station Configuration Message.
