From e41266b57cfaf00cc9e1c2133a4c5e12dc661f95 Mon Sep 17 00:00:00 2001 From: Rasesh Mody Date: Mon, 18 Sep 2017 18:29:44 -0700 Subject: [PATCH] net/qede/base: allocate VF queues before PF Change the order by which we allocate the resources to align with management FW by first allocating the VF l2 queues and only afterwards use what's left for the PF.
