Subject[patch 2/27] Fix 3c59x driver for some 3c566B's


Fix from Rahul Karnik and Donald Becker - some new 3c566B mini-PCI NICs
refuse to power up the transceiver unless we tickle an undocumented bit
in an undocumented register. They worked this out by before-and-after
diffing of the register contents when it was set up by the Windows
driver.
