Subject: [PATCH v9 iwl-next 10/12] ice: Add NAC Topology device capability parser
From: Grzegorz Nitka <grzegorz.nitka@...el.com>
Add new device capability ICE_AQC_CAPS_NAC_TOPOLOGY which allows to
determine the mode of operation (1 or 2 NAC).
Define a new structure to store data from new capability and
corresponding parser code.
