ath6kl: Implement support for QOS-enable and QOS-disable from userspace
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 kvalo: minor commit log cleanup Signed-off-by: Rishi Panjwani <rpanjwan@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>hifive-unleashed-5.1
