Date: Mon, 16 May 2016 11:15:43 -0700 From: Dave Taht <dave.taht@...il.com> To: Luca Coelho <luca@...lho.fi> Cc: Dan Carpenter <dan.carpenter@...cle.com>, Sara Sharon <sara.sharon@...el.com>, linux-wireless <linux-wireless@...r.kernel.org>, "netdev@...r.kernel.org" <netdev@...r.kernel.org> Subject: Re: iwlwifi: mvm: add reorder buffer per queue I can't even describe how much I hate the concept of the reorder buffer in general. Ordering is the endpoints problem. Someday, after we get fq_codeled, short queues again, I'll be able to show why.
