OK, that seems to be a value that is not supported by iwconfig rate
command. Since I already added iwpriv param for setting basic rate set,
I will add your patch for operational TX rate setting as a similar bit
map. In the future, it might be useful to change these to be normal
wireless ext ioctls, i.e., new or modified ioctl for setting and getting
basic and operational rate sets as bit maps of supported rate list
(iwlist rate).

Jean, do you have an opinion on this? Setting TX rate to 5.5 + 11, but
not 1 and 2 Mbps seems reasonable configuration in some environments and
basic rate set configuration would be useful for Master mode (it is even
required in Wi-Fi certification of an AP).
