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
