Intel are limiting which SFP's can use in their NICs, due to support issues. This restriction comes from an EEPROM setting IXGBE_DEVICE_CAPS_ALLOW_ANY_SFP. This is for example the case with the 10Gbit/s X520-DA2 NIC. Add a module param "allow_any_sfp", which can override the EEPROM setting, and allows any unsupported SFP+ module to be used. When doing so, print disclaimer of unsupported usage.
