Well it depends on the DLC, and it depends on what needs to be updated.
There has been 3 mutliplayer updates so far, and from what I remember they've all been around 2 gigs.
But you don't have to have them all downloaded, you may delete previous updates, as you will only need the latest (assuming it doesn't automatically delete them).
Edit: Seems I was misinformed. To play the back to karkand map pack, you will need update 2.
