Subject: [PATCH ethtool 18/19] netlink: add netlink handler for sset (-s)
Implement "ethtool -s <dev>" subcommand using netlink interface request
ETHTOOL_MSG_LINKINFO_SET, ETHTOOL_MSG_LINKMODES_SET, ETHTOOL_MSG_WOL_SET
and ETHTOOL_MSG_DEBUG_SET.
Parser grouping with PARSER_GROUP_MSG group style is used to create
multiple request messages from one set of attributes which can be in
arbitrary order.
