From 341bd4e07d6615ecc22a8c5bdf4c53efe414cb55 Mon Sep 17 00:00:00 2001 From: Igor Romanov Date: Thu, 24 Sep 2020 13:12:18 +0100 Subject: [PATCH] common/sfc_efx/base: add function control window concept Function control window can be located at a different offset than other windows on Riverhead. Meaning that the drivers must handle accesses to the function control window differently in case of EF100. Add accessor macros for function control window and change EFX NIC create API to facilitate that accessors.
