Subject: [PATCH AUTOSEL 5.2 155/171] net/mlx5: E-Switch, Fix default encap mode

From: Maor Gottlieb <maorg@...lanox.com>

[ Upstream commit 9a64144d683a4395f57562d90247c61a0bf5105f ]

Encap mode is related to switchdev mode only. Move the init of
the encap mode to eswitch_offloads. Before this change, we reported
that eswitch supports encap, even tough the device was in non
SRIOV mode.

Fixes: 7768d1971de67 ('net/mlx5: E-Switch, Add control for encapsulation')
