I'm on it.

I tried with  the wm driver.  This one I could switch to cross cable then back to the switch or force the switch to 
100Mbits and it works fine.  As for the performance it looks ok but within 2-3 minutes of light network activity ( pidin
 -n ) io-pkt will sigsegv or it will display the "Out of interrupt event message"

I haven't tried devnp-i82544 yet.

I tried with both wm and devnp-i82544, both detect speed/duplex setting just fine.

devnp-i82544 is slow, even at 100Mbits ( so it's not timing issues with 1000Mbits )

with wm it seems fast as expected but hard to say because it crashes before I have time to run enough test.

I will try 6.3.2 devn-i82544 which is a pain because we have to specify the MAC addresses and device/vendor id, but 
maybe it will give you guys some clues where to look.

Meanwhile I'll talk to our management  to get them to talk with QSS sales rep to try to escalate this ( even send you 
hardware )
