Description (partial)

- Right now slot0 will copy slot1’s tx power dBm instead of the power level index.
- I believe we can make the decision making better since we run into problems when facing a configuration that looks like this:

- RF profile configured for APs to use 7dB
========RF Profile
Min Transmit Power............................... 7 dBm
Max Transmit Power............................... 7 dBm

- Based on the channel and antenna gain used, those are the power levels on slot1. Slot 1 has no 7 dB level so it gets 6 
Serving Frequency: 5280Mhz Channel: 56 20MHz
Configured Antenna Gain(dBi): 13
Configured Level: 2
Configured TxPower(dBm): 6
Total Supported Power Levels:4
Allowed total powers(dBm):
9 6 3 2 
- Slot 0 check thats slot 1 is using 6dB, finds out it has no 6 db so it gets 4
- Slot 0 uses 6dB even though its got 7dB as one of its power levels
Serving Frequency: 5180Mhz Channel: 36 20MHz
Configured Antenna Gain(dBi): 6
Configured Level: 5
Configured TxPower(dBm): 4        
Total Supported Power Levels:6
Allowed total powers(dBm):
16 13 10 7 4 2 

- Slot 0 should check what min/max transmit power is configured in the RF profile as well as what slot1 is using
- On slot 1 maybe we can also check what power levels are allowed based on the RF profile before assigning a channel that wouldn't support that power level

- WLC image:
- 3802P/2802P APs used with a DART smart connecter and both radios on 5GHz.
