swp_l4_csum_mode controls how L4 transmit checksums are computed when
using Software Parser (SWP) hints for header locations.

Supported values:
 1. device_default: use device default setting.
 2. full_csum: calculate L4 checksum with the pseudo-header.
 3. l4_only: calculate L4 checksum without the pseudo-header. Only
    available when swp_l4_csum_mode_l4_only is set in
    mlx5_ifc_nv_sw_offload_cap_bits.

The l4_only setting is a dependency for PSP initialization in
mlx5e_psp_init().

Daniel, I asked twice if this could be a non-driver param. Jakub asked
for clearer definition of this know in that context.

Not sure why you are ignoring this :/
