[PATCH v2 086/148] net/ice/base: add defines for loopback mode

[Anatoly Burakov]

From: Ian Stokes <ian.stokes at intel.com>

To reflect updates in the data sheet, add:

- loopback mode value into ice_aqc_set_port_params
- required defines to support loopback mode
- added loopback mode handling in ice_port_info
