> Subject: [dpdk-dev] [PATCH v4 0/8] net/mlx5: consolidate Tx datapath
> 
> This patchset introduces the new implementation of tx_burst routine of mlx5
> PMD. The existing implementation is based on the several branches of
> tx_burst routines optimizied for most common sets of Tx hardware offload,
> supported by Mellanox NICs.
> 
> It was not very easy to update, support and develop such kind of code -
> multiple branches impose multiple points to process.
> Also, many of frequently requested offload combinations are not supported
> yet in the most efficient way. That leads to selecting of not completely
> matching tx_burst routine and harms the performance.
> 
> The new Tx datapath:
>   - introduces the unified template for tx_burst routine to generate
>     on compile time the most efficient instances, tuned for specified
>     sets of hardware offloads
>   - the best matching instance is chosen in run-time at sending queue
>     configuration
>   - almost all possible sets of Tx are supported
>   - the best possible method to send each packet is chosen on runtime
>   - introduces new devargs for more accurate tuning of data inlining
