[SUNGEM]: PHY updates & pause fixes (#2)
This patch adds support for a few more PHYs used by Apple and fixes advertising and detecting of Pause (we were missing setting the bit in MII_ADVERTISE and weren't testing in LPA for all PHYs). Note that I currently only advertise pause, not asymetric pause. I don't know for sure the details there, I suppose I should read a bit more 802.3 references, and I don't now what sungem is capable of, but I noticed the PCS code (originated from you) does the same.
