net/mlx5: remove Rx queues indexes correlation
There is a full correlation between the CQE indexes to the WQE indexes in the vectorized Rx queues management. When the RQ is inserted to the reset state, the correlation may break because the HW starts the RQ polling from index 0 while the CQ polling continues regularly. As an arrangement to CQE errors handling, when the RQ can be reset, the correlation dependence should be removed from all the Rx queues index managements. Remove the aforementioned dependence from the vectorized Rx burst functions. Cc: stable@dpdk.org Signed-off-by: Matan Azrad <matan@mellanox.com> Acked-by: Shahaf Shuler <shahafs@mellanox.com>
