thorpej 94e489e277 If the autonegotiation is enabled, the PAR doesn't indicate duplex mode 
properly!  Work around this by determing current active media by taking
the highest-order common bit of our advertised capabilites and the link
partner's.

If the link partner doens't do autonegotiation, then parallel detection will
pick up the media type, which will never be full-duplex, so reading the PAR
is ok in this case.

Bug pointed out by Matthias Drochner, work-around inspired by reading
the dp83840 manual, section 3.9 (IEEE 802.3u auto-negotiation).
