  The problem though is that while the card and the switch _do_ happily
negotiate full duplex, as soon as ifconfig runs, the driver messes it up,
turning off full duplex, no matter what I specify.  So the problem is not
with the card, but apparently with the driver.  I gather then that what
you're telling me is that until tlp does NWAY, I'm out of luck.  Is that
right?  Is there some way I can tell/patch tlp to not mess with the
autonegotiated speed/duplex settings?
