ethtool: wire up get policies to ops
Wire up policies for get commands in struct nla_policy of the ethtool family. Make use of genetlink code attr validation and parsing, as well as allow dumping policies to user space. For every ETHTOOL_MSG_*_GET: - add 'ethnl_' prefix to policy name - add extern declaration in net/ethtool/netlink.h - wire up the policy & attr in ethtool_genl_ops[]. - remove .request_policy and .max_attr from ethnl_request_ops. Obviously core only records the first "layer" of parsed attrs so we still need to parse the sub-attrs of the nested header attribute. v2: - merge of patches 1 and 2 from v1 - remove stray empty lines in ops - also remove .max_attr Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.
