Subject: [PATCH RFC 01/18] r8169: split driver to one for the non-PCIE cards
(r8169) and one for the PCIE cards (r8168)
A significant part of the code is specific to either the old non-PCIE
cards or the newer PCIE cards. In addition the non-PCIE cards partially
support a not MII-compatible TBI fibre mode.
Therefore split driver to one for the non-PCIE cards (r8169) and one
for the PCIE cards (r8168).
