Registering Generic Netlink Families and Commands.
| int genl_register_family | ( | struct genl_ops * | ops | ) |
Register Generic Netlink family and associated commands.
| ops | Generic Netlink family definition |
Registers the specified Generic Netlink family definition together with all associated commands. After registration, received Generic Netlink messages can be passed to genl_handle_msg() which will validate the messages, look for a matching command and call the respective callback function automatically.

Same as genl_register_family() but additionally registers the specified cache operations using nl_cache_mngt_register() and associates it with the Generic Netlink family.
