Are you sure this is not the FW that controls the data path?  

There is only one FW rev to report, and this covers mgmt and data.  

Can you add a key for that? Cause this one clearly says management..  

Perhaps something like this?

/* Overall FW version */
#define DEVLINK_INFO_VERSION_GENERIC_FW    "fw"

Sounds reasonable.

Since I don't have any board info available at this point, shall I use
my own "asic.id" and "asic.rev" strings, or in this patch shall I add
something like this to devlink.h and use them here:

/* Part number, identifier of asic design */
#define DEVLINK_INFO_VERSION_GENERIC_ASIC_ID    "asic.id"
/* Revision of asic design */
#define DEVLINK_INFO_VERSION_GENERIC_ASIC_REV    "asic.rev"  

Yes, please add these to the generic items and document appropriately.  

Sure.  Is there any place besides 
Documentation/networking/devlink-info-versions.rst?

Nope, that's the one.
