In the title and commit log, can you please capitalize the abbreviation VSI, so
that VSIs is recognisable as a plural of the acronym, and not as the word "vsis",
which confused me for a while. :-)

Can you also explain what ETS stands for. [Not sure if VSI also needs to be 
expanded out the first time it is used in the message]

Suggest to reword this as: "Added support for DCB in VMDQ mode to i40e driver"
