From 86d36773bd42bda39e7cadaa7dc067d67b833230 Mon Sep 17 00:00:00 2001 From: Igor Russkikh Date: Fri, 12 Oct 2018 11:09:14 +0000 Subject: [PATCH] net/atlantic: implement firmware operations AQC NICs comes in fields with two major FW generations: 1x and 3x. This is part of linux atlantic driver shared code, responsible for internal NIC firmware interactions, including link management ops, FW initialization, various lifecycle features.
