I was donated some hardware, including an Intel 10G card with 2x SFP+ slots. However, I can't figure out if this is the '-SR2' (compatible with fiber modules) or '-DA2' (intended for DAC only) model within the X520 series. As far as I can tell, these cards look identical to the naked eye. Is it possible to tell which it is from within FreeBSD, or is it basically trial and error with modules?
A little info on it:
My hunch is both these cards looks identical to the OS as they have no way of knowing which is which, but I'd love to be proven wrong.
