Date: Wed, 24 Aug 2022 14:20:09 +0200 From: Jiri Pirko <jiri@...nulli.us> To: netdev@...r.kernel.org Cc: davem@...emloft.net, kuba@...nel.org, idosch@...dia.com, pabeni@...hat.com, edumazet@...gle.com, saeedm@...dia.com, jacob.e.keller@...el.com, vikas.gupta@...adcom.com, gospo@...adcom.com Subject: [patch net-next v3 1/3] net: devlink: extend info_get() version put to indicate a flash component From: Jiri Pirko <jiri@...dia.com> Whenever the driver is called by his info_get() op, it may put multiple version names and values to the netlink message. Extend by additional helper devlink_info_version_running/stored_put_ext() that allows to specify a version type that indicates when particular version name represents a flash component. This is going to be used in follow-up patch calling info_get() during flash update command checking if version with this the version type exists.
