[PATCH] net/mlx5: fix gtp handling in header modify action

[PATCH] net/mlx5: fix gtp handling in header modify action

[Dariusz Sosnowski]

GTP items were ignored during conversion of modify header actions. This
caused modify TTL action to generate a wrong modify header command when
tunnel and inner headers used different IP versions.

This patch adds GTP item handling to modify header action conversion.
