There is one problem with netgraph on 64-bit platforms. The ng_msghdr

would be nice to fix that (and bump NG_VERSION, of course). Nobody
ever guaranteed that the message payload would be aligned, but it
makes things a lot more convenient.
if we do this we should do it now so that we have a consistent ABI from 5.3 on..
scott (et al), should we pad an extra 4 bytes in this now?
it's low/no risk, but better now than after 5.3 has been released..
I'd really like to see this change happen. Julian, would it require
bumping just NG_VERSION, or should NG_ABI_VERSION change too?

The first step here is to commit to HEAD. Once the details are worked
out, we'll likely approve it for RELENG_5.
