From: Eric Kinzie Date: Thu, 24 Mar 2016 21:59:58 +0000 (-0700) Subject: bonding: use existing enslaved device queues X-Git-Tag: spdx-start~7164 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5b7bb2bda5519b7800f814df64d4e015282140e5;p=dpdk.git bonding: use existing enslaved device queues This solves issues when an active device is added to a bond. If a device to be enslaved already has transmit and/or receive queues allocated, use those and then create any additional queues that are necessary.
