PCI MSI for re(4)

[Paul Goyette]

Attached is a patch that should enable PCI MSI for pci(4)-attached
re(4) NICs. I would like both review of the code, and additional
testing.
I've tested it successfully on amd64 -current with a
8100E/8101E/8102E/8102EL chip.

I've been running with this for a couple weeks now, and everything just
works. No issues seen.

Are you planning to commit the changes soon?

I'll probably commit it soon, because it doesn't look like I'll be
getting to MSI for Tegra K1 soon.
