As a datapoint: We had a customer trying to use a non-supported SFP+ module in an 82599 NIC, and they hacked the driver to over-rule the exclusion. It sort of worked for them, but never well, and never at any decent throughput. Now, I have no idea if their SFP+ was decent or not, but at least in some cases, just over-riding the driver doesn't fix things. It does seem like Intel could offer a module option to easily over-ride the SFP+ exclusion for folks that wanted to test new SFP+ modules for them, however.
