> Subject: [PATCH] net/mlx5: fix vectorized Rx burst termination
>
> Maximum burst size of Vectorized Rx burst routine is set to
> MLX5_VPMD_RX_MAX_BURST(64). This limits the performance of any
> application that would like to gather more than 64 packets from
> the single Rx burst for batch processing (i.e. VPP).
>
> The situation gets worse with a mix of zipped and unzipped CQEs.
> They are processed separately and the Rx burst function returns
> small number of packets every call.
>
> Repeat the cycle of gathering packets from the vectorized Rx routine
> until a requested number of packets are collected or there are no
> more CQEs left to process.
