My other 82599 NICs have been running fine with other SFP+ modules.

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 :-) -- Best regards, Jesper Dangaard Brouer ComX Networks A/S Linux Network Kernel Developer Cand.
