Subject: [PATCH mlx5-next 06/10] net/mlx5: Introduce extended destination fields

From: Eli Britstein <elibr@...lanox.com>

Extended destinations provide the ability to configure different
encapsulation properties per destination on a single FTE. This is
needed for use-cases such as remote mirroring over tunneled networks.
