I think the bnxt team is doing what they can to make as much information available as possible. In this case, they seem to be trying to make versioning info about the firmware package available along with the info about the firmware version itself, and together just barely overflowing the available space in the ethtool structure.
I'll leave it to you and/or Broadcom to determine whether or not that is a bug that needs to be changed.
In the meanwhile, from your quoted message it seems that lspci can give you the correct package version information for the device.
Good luck!
John
