Yeah I started converting all drivers across to skb_align and quickly
noticed that. We can instead convert drivers over as they are tested,
the Gbit and 10Gbit cards being the most important.

Ive tested the 2 10Gbit cards and one 1Gbit (e1000). I can test the
acenic and should be able to hunt down a sungem and tg3.

That leaves dl2K, myricom, ns83820, hamachi, yellowfin, r8169, and sk98lin
which can be converted across as needed.
