In order to allow user space based control of background scan interval,
we use available debugfs infrastructure. The feature has been added for
testing purposes. The user has to write the bgscan interval (in secs) to
the bgscan_interval file in ath6kl debug directory. To disable bgscan,
a '0' is to be written to the bgscan_interval file.

Example:

echo "2" > bgscan_interval

This will make the background scan interval as 2 seconds

In order to allow user space based QOS control we use the available debugfs
infrastructure. With this feature, user can make changes to qos parameters,
thereby allowing creation and deletion of user defined priority streams and
features like uapsd. This feature has been added for testing purposes.

All 21 parameters for the create_qos command are mandatory in the correct
order. They have to be written to the create_qos file in
the ath6kl debug directory. These parameters(in order) are:

1)user priority
2)direction
3)traffic class
4)traffic type
5)voice PS capability
6)min service intvl
7)max service intvl
8)inactivity intvl
9)suspension intvl
10)serv start time
11)tsid
12)nominal msdu
13)max msdu
14)min data rate
15)mean data rate
16)peak data rate
17)max burst size
18)delay bound
19)min phy rate
20)surplus bw allowance
21)medium time

To create a qos stream:

echo "6 2 3 1 1 9999999 9999999 9999999 7777777 0 6 45000 200 56789000
56789000 5678900 0 0 9999999 20000 0" > create_qos

delete_qos requires 2 parameters:

1)traffic class
2)tsid

To delete a qos stream:

echo "3 1" > delete_qos

The previous version did not really make much sense and the theoretical
maximum length would be a bit longer. Calculate the length more
accurately. In addition, there is no need to clear the buffer, so use
kmalloc instead of kzalloc. For bonus points, add the forgotten
