Subject: [PATCH net-next 10/13] mlxsw: Add ubridge to config profile

From: Amit Cohen <amcohen@...dia.com>

The unified bridge model is enabled via the CONFIG_PROFILE command
during driver initialization. Add the definition of the relevant fields
to the command's payload in preparation for unified bridge enablement.
