[patch net-next v2 11/15] devlink: move port_fn_roce_get/set() to devlink_port_ops

[Jiri Pirko <jiri@resnulli.us>]

From: Jiri Pirko <jiri@nvidia.com>

Move port_fn_roce_get/set() from devlink_ops into newly introduced
devlink_port_ops.

Signed-off-by: Jiri Pirko <jiri@nvidia.com>
---
v1->v2:
- avoid ops check as they no longer could be null
