From a824d012ad8f736459398e9c1d5bc0f034c72e5e Mon Sep 17 00:00:00 2001 From: Daniel Jurgens Date: Tue, 11 Jul 2023 00:28:10 +0300 Subject: [PATCH] net/mlx5: Allow 0 for total host VFs commit 2dc2b3922d3c0f52d3a792d15dcacfbc4cc76b8f upstream. When querying eswitch functions 0 is a valid number of host VFs. After introducing ARM SRIOV falling through to getting the max value from PCI results in using the total VFs allowed on the ARM for the host.
