The 'QM_INIT' and 'QM_CLOSE' status of qm and 'QP_INIT' and 'QP_CLOSE' status of queue are not actually used. Currently, driver only needs to switch status when the device or queue is enabled or stopped, Therefore, remove unneeded status to simplify driver. In addition, rename'QM_START to'QM_WORK' for ease to understand. Signed-off-by: Weili Qian <qianweili@huawei.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Description: The <bdf> is related the function for PF and VF.

ZIP driver supports to configure each function's QoS, the driver
|
|
supports to write <bdf> value to alg_qos in the host. Such as
|
|
"echo <bdf> value > alg_qos". The qos value is 1~1000, means
|
|
1/1000~1000/1000 of total QoS. The driver reading alg_qos to
|
|
get related QoS in the host and VM, Such as "cat alg_qos".
