They only support two fiber optics SFP+ module!!! ... sorry but that
sucks :-(
Does anybody know why they can only support these two SFP+ modules?
My other 82599 NICs have been running fine with other SFP+ modules.
Is there a technical reason?

I fully understand, you cannot support these engineering samples.
Do Intel have another model of NICs, that support more SFP+ modules?
Perhaps the x540 based one?
(I would like support for a 20Km SFP+)
Thanks for your answer, Jesse :-)
