# Script to run on the target to configure the wl18xx-conf.bin file to match the device capabilities and 
# antennae configuration. Takes as an argument the device name - wl1801,wl1805, wl1831, wl1835

# logic to be followed here is that if a device has a parameter with a value over 1 then there is a choice 
# that has to be made by user as to whether the feature will be used.
# eg a 2.4GHz MIMO capable device may only have a single antenna fitted
# assume that as 2.4GHz does not pass WFA test with 40MHz channels then we disable it for ALL devices
