enable_roce: RoCE enablement state

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

RoCE enablement state controls driver support for RoCE traffic.

When RoCE is disabled, there is no gid table, only raw ethernet QPs are supported and traffic on the well-known UDP RoCE port is handled as raw ethernet traffic.

If the device supports RoCE disablement, RoCE enablement state controls device

support for RoCE capability. Otherwise, the control occurs in the driver stack.

When RoCE is disabled at the driver level, only raw ethernet QPs are supported.



To change RoCE enablement state, a user must change the driverinit cmode value and run devlink reload.
