SRU justification:

Impact: This was reported as a regression against Intrepid. The change that
most likely caused this was a fix (which was now asked for Hardy by another
user) to remove access to a certain register for cards other than 8169.
Unfortunately the code uses in some cases the PCI information but in other
cases the MAC version to decide how to handle a card. For those cards in
question the 8101 code is used to initialize the cards hardware but for other
aspects the unknown MAC causes it to be handled as a 8169 card.

The fact that those cards worked before seems to be pure luck.

Fix: The following 5 patches taken from upstream adds proper support for those
cards.


Testcase: Networking was impossible before and has been verified to be working
after by 2 users.
