net/mlx5e: Introduce extended version for mlx5e_xmit_data
Introduce struct mlx5e_xmit_data_frags to be used for non-linear xmit
buffers. Let it include sinfo pointer.
Take one bit from the len field to indicate if the descriptor has
fragments and can be casted-up into the extended version.
Zero-init to make sure has_frags, and potentially future fields, are
zero when not explicitly assigned.
Another field will be added in a downstream patch to indicate and point
to dma addresses of the different frags, for redirect-in requests.
This simplifies the mlx5e_xmit_xdp_frame/mlx5e_xmit_xdp_frame_mpwqe
functions params.
