it will be good to use imperative mood in the Subject,
and add one more paragraph, like:

Subject: e1000: mark global variables const where possible

Next paragraph:
Mark global variables const, so unintended modification would not be
possible.

your commit message suggests that you add const "everywhere", but it
seems that there are other candidates, like the one above

PS. You have to wait 24h before posting next revision.

I'd suggest 'fix' 
e1000: fix global variables const where possible
But anyway the change is useful and so small and well-understandable.
