Subject: [PATCH 4.17 08/31] net/mlx5e: E-Switch, Initialize eswitch only if eswitch manager

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eli Cohen <eli@...lanox.com>

[ Upstream commit 5f5991f36dce1e69dd8bd7495763eec2e28f08e7 ]

Execute mlx5_eswitch_init() only if we have MLX5_ESWITCH_MANAGER
capabilities.
Do the same for mlx5_eswitch_cleanup().

Fixes: a9f7705ffd66 ("net/mlx5: Unify vport manager capability check")
