Mostly consistency. The current nvme host code has the EUI sprinkled all
around. Sure I can drop it, but then what's the point in evaluating it
on the host side? Other targets may send it, so we need in on the host
and do we care about potentially awkward host implementations with Linux
as a target? Also it's rather handy for testing as well, after all it's
not too much and complex code.
