> Subject: [PATCH v2 0/4] net/mlx5: remove Tx descriptor reserved field usage
> 
> The current Tx datapath implementation in mlx5 PMD uses the 16-bit
> reserved field within transmit descriptor to store the indices of the elts array
> keeping the mbuf pointers to be freed on transmit completion. On
> completion PMD fetches the descriptor index, then fetches the elts array
> index from reserved field and frees the mbufs.
> 
> The new ConnectX-6DX NIC might use this reserved descriptor field and
> existing implementation might not work in intended way.
> To resolve this issue the dedicated buffer is introduced to store indices to
> instead of descriptor field.
