I think it's better to put this on the backburner for now :-)

We could achieve all of this if we start from the bottom
and work our way up.

Although there are many variations, the logic drivers use to use
skb_reserve() to align the receive header tends to take on a certain
pattern.  We could pull that out into a common piece of code and then
make it ensure 64-bit alignment without a lot of pain.

The hard part of the work will be handling the cases that don't
fit the pattern, and don't forget about NET_IP_ALIGN :-)
