Group cipher is used for broadcast/multicast frames and as such, it must
be shared with all clients and as such, there can only be one group
cipher and it has to be the least secure (well, the most likely to be
implemented) cipher from the ones enabled as pairwise ciphers.

TKIP CCMP must be in a single command line argument, i.e., use
set_network "TKIP CCMP" on the command line.
