Implement CHANNELS_SET netlink request to set channel counts of a network device. These are traditionally set with ETHTOOL_SCHANNELS 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. Checks preventing removing channels used for RX indirection table or zerocopy AF_XDP socket are also implemented. Move ethtool_get_max_rxfh_channel() helper into common.c so that it can be used by both ioctl and netlink code. v2: - fix netdev reference leak in error path (found by Jakub Kicinsky) Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.
