Subject: Re: [Intel-wired-lan] [next-queue PATCH 7/8] igb: Add support for
adding offloaded clsflower filters
Hi Vinicius,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on jkirsher-next-queue/dev-queue]
[also build test WARNING on v4.16-rc2 next-20180223]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
