d68bc01d00 change supportedrates config setting to the actual MBit value 
supportedrates is now a list instead on an array and float values
(e.g. 5.5) are permited.

8dc30ae3c4 rework socket and discovery handling 
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.

9fee37a994 rework wifi type and rate logic 
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.

b80073b756 inject 802.11 frames through the normal device queue 2016-02-25 12:39:19 +01:00
Andreas Schultz
0c19932b58 send 802.3 frames through the normal device TX path 
Injecting 802.11 frames underneath the device logic bypasses
the queue logik and leads to delay. Pass 802.3 frames through
the normal device TX chain.

This has the added benefit that AF_PACKET sockets (e.g. tcpdump)
see the send frames.

a6d0efe91a wtp: rework kernel socket handling 
Switch to a connected UDP kernel socket. Comparing the
local and remote IPs is no longer required and handling
different IP versions and UDP types is automatic.

The WTP logic needs to reopen the socket on demand now.
