From: Johannes Berg Date: Wed, 28 Mar 2012 09:04:26 +0000 (+0200) Subject: mac80211: decouple # of netdev queues from HW queues X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ded81f6ba934e792e441f20178683608cbc0b5cb;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git mac80211: decouple # of netdev queues from HW queues When we get more hardware queues, we'll still want to only have netdev queues per AC, so set it up in that way. If the hardware doesn't support QoS (by not supporting at least 4 queues) the netdevs get a single queue only (this is no change in behavior as there are no drivers with 2 or 3 queues today.)
