We actually have a mix of styles, some using double-indent on continuation, and
some using aligning as above. I prefer the double indent, as I don't like mixing
tabs and spaces for indentation and the resulting line-up of lines for those poor
souls using 4-char tabs, but overall, the global rule is to try and copy the
existing style in the file being modified. There are already instances of
this style of indent in ethdev.c [I checked, which is why I didn't object myself
to Stephen's comment :-)]
