Significant part of GET request processing is common for most request types but unfortunately it cannot be easily separated from type specific code as we need to alternate between common actions (parsing common request header, allocating message and filling netlink/genetlink headers etc.) and specific actions (querying the device, composing the reply). The processing also happens in three different situations: "do" request, "dump" request and notification, each doing things in slightly different way. The request specific code is implemented in four or five callbacks defined in an instance of struct get_request_ops: parse_request() - parse incoming message prepare_data() - retrieve data from driver or NIC reply_size() - estimate reply message size fill_reply() - compose reply message cleanup_data() - (optional) clean up additional data Other members of struct get_request_ops describe the data structure holding information from client request and data used to compose the message. The default handlers ethnl_default_doit(), ethnl_default_dumpit(), ethnl_default_start() and ethnl_default_done() can be then used in genl_ops handler. Notification handler will be introduced in a later patch. Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
