Forgot to mention the following in ChangeLog:
* Added private ioctl to set the network type to a specific type. Use
"iwpriv wlan0 network_type <char>" to set the network type to what <char>
represents, where <char> is one of a, b, g or any other characther.
For example, to set to 802.11b, use "iwpriv wlan0 network_type b",
and to set to auto, "iwpriv wlan0 network_type x".
Note that you don't usually need to set the type to b/g. NDIS specifies that
the driver should set the type to "auto", which will pick up any network type.
However, it may help to set the type of cards that support all three types
(abg cards) to either a or b/g. Network type should be set before associating.
