    ethtool: wire up get policies to ops · 4f30974f
    Jakub Kicinski authored
    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
