Subject: [patch net-next v3 1/3] net: devlink: extend info_get() version put to indicate a flash component
Date: Wed, 24 Aug 2022 14:20:09 +0200	[thread overview]
Message-ID: <20220824122011.1204330-2-jiri@resnulli.us> (raw)
In-Reply-To: <20220824122011.1204330-1-jiri@resnulli.us>

From: Jiri Pirko <jiri@nvidia.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.
