I'll also note this seems to be somewhat unpredictable. I installed a dual port intel 10GbE card into one of the systems, I have not plugged SFP+ modules into them, and three out of four interfaces were available with the fourth completely AWOL. Rebooting with hw.ix.unsupported_sfp=1 presented all four, as expected.
As for a use case as to why someone would want this, building out systems before deployment comes to mind. Thanks!
