From 2fc2929e807211a9535a6541f24b57fa1c469728 Mon Sep 17 00:00:00 2001 From: Michal Kubecek Date: Thu, 12 Mar 2020 21:08:28 +0100 Subject: ethtool: set device ring sizes with RINGS_SET request Implement RINGS_SET netlink request to set ring sizes of a network device. These are traditionally set with ETHTOOL_SRINGPARAM ioctl request. Like the ioctl implementation, the generic ethtool code checks if supplied values do not exceed driver defined limits; if they do, first offending attribute is reported using extack. v2: - fix netdev reference leak in error path (found by Jakub Kicinsky) Signed-off-by: Michal Kubecek Reviewed-by: Jakub Kicinski Signed-off-by: David S.
