The short options should only include one letter.  Also the general
pattern is that 'get' options use lower-case letters and 'set' options
use upper-case letters.  No, I'm not sure how best to handle a set of 3
options.  Maybe you can combine --get-dump and --get-dump-data, making
the filename optional?

ethtool already has "-f" option to flash/write the FW image.
Can you use "-F" to get the FW dump data out?
And then may be, these options can be extended to get the get/set dump levels?
