Subject: net/qede/base: allocate VF queues before PF
X-Git-Tag: spdx-start~1938
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e41266b57cfaf00cc9e1c2133a4c5e12dc661f95;p=dpdk.git

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.
