[PATCH] Sun HME: enable and map PCI ROM properly
This ports the Sun GEM ROM mapping/enable fixes it sunhme (which used the same PCI ROM mapping code). Without this, I get NULL MAC addresses for all 4 ports (it's a SUN QFE). With it, I get the correct addresses (the ones printed on the label on the card). Signed-off-by: Linus Torvalds <torvalds@osdl.org>
