From a399ed9ae4df3a6e76d1bd9b7960520d125e66ef Mon Sep 17 00:00:00 2001 From: Rory Sexton Date: Wed, 11 Oct 2017 17:18:47 +0100 Subject: [PATCH] net/i40e: support converting VF MAC to VF id Need a way to convert a VF id to a PF id on the host so as to query the PF for relevant statistics which are used for the frequency changes in the vm_power_manager app. Used when profiles are passed down from the guest to the host, allowing the host to map the VFs to PFs.
