This command is used to manually set the driver capabilities flags. This is normally used for testing, since the
driver itself will fill in the proper capability flags. The flags are defined as follows:

dtim_period
delivery period
This is used to set the Delivery Traffic Indication Map (DTIM) period. The DTIM is an interval specified by
the AP to the station indicating when multicast traffic may be available for the station, requiring the STA to be
awake to receive the messages. This command will set the AP’s DTIM period, in milliseconds. A longer
DTIM will provide for a greater power savings, but will increase multicast latency. This parameter has a
default value of 1 millisecond. There is a corresponding get command.

fastcc 1|0
This enables fast channel change. A value of 1 indicates that channel changes within band will be done without
resetting the chip. A value of 0 indicates that any channel change will require a chip reset. This command has a
corresponding get command, and its default value is 0
