If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From foo@baz Tue Jan 26 21:37:04 PST 2016 From: Wei Liu <wei.liu2@xxxxxxxxxx> Date: Thu, 10 Sep 2015 11:18:58 +0100 Subject: xen-netfront: respect user provided max_queues From: Wei Liu <wei.liu2@xxxxxxxxxx> [ Upstream commit 32a844056fd43dda647e1c3c6b9983bdfa04d17d ] Originally that parameter was always reset to num_online_cpus during module initialisation, which renders it useless. The fix is to only set max_queues to num_online_cpus when user has not provided a value.
