64 * traffic classes (ETS) and configured rate limit for traffic classes.
65 * tc_tx_bw, pg and ratelimit are arrays where each index represents a TC.
66 * The description for those parameters below refers to a single TC.

70 * @tc_tx_bw: The percentage of the bandwidth allocated for traffic class
71 * within a TC group. The sum of the bw_percentage of all the traffic
72 * classes within a TC group must equal 100% for correct operation.
73 * @pg: The TC group the traffic class is associated with.

97 * the value reported by availible_vpp in mlx4_ALLOCATE_VPP_get.
98 * VPP allocation is allowed only after the port type has been set,

111 * Each priority allowed for the Vport is assigned with a share of the BW,
112 * and a BW limitation. This commands query the current QoS values.
115 * @port: Physical port number.

126 * QoS parameters can be modified at any time, but must be initialized
127 * before any QP is associated with the VPort.
130 * @port: Physical port number.
132 * @out_param: Array of mlx4_vport_qos_param which holds the requested values.
134 * Returns 0 on success or a negative mlx4_core errno code.
