[dpdk-dev] [PATCH 4/8] net/mlx4: optimize Tx multi-segment case

mlx4 Tx block can handle up to 4 data segments or control segment + up to 3 data segments. The first data segment in each not first Tx block must validate Tx queue wraparound and must use IO memory barrier before writing the byte count. The previous multi-segment code used "for" loop to iterate ov
