net/mlx5e: IPsec: Fix crypto offload for non TCP/UDP encapsulated traffic
[ Upstream commit5352859b3b
] IPsec crypto offload always set the ethernet segment checksum flags with the inner L4 header checksum flag enabled for encapsulated IPsec offloaded packet regardless of the encapsulated L4 header type, and even if it doesn't exists in the first place, this breaks non TCP/UDP traffic as such. Set the inner L4 checksum flag only when the encapsulated L4 header protocol is TCP/UDP using software parser swp_inner_l4_offset field as indication. Fixes:5cfb540ef2
