IMHO, this information is very useful and only takes up very little
log file space. :-)

If it's critical then the log is the wrong place for it as the log
is lossy.

The proper place to obtain this information is via the fw_version
field of the ethtool_drvinfo struct.  This can be obtained at any time
and is reliable.  And if it isn't reliable or correct, we must fix
that.
