Note that this requirement is implemented in the driver.  YMMV depending
on OS, but in Linux you can disable it with the usual warnings by
setting 'allow_unsupported_sfp=3D1' :

 bjorn@canardo:~$ modinfo -p ixgbe
 max_vfs:Maximum number of virtual functions to allocate per physical funct=
ion - default is zero and maximum value is 63. (Deprecated) (uint)
 allow_unsupported_sfp:Allow unsupported and untested SFP+ modules on 82599=
-based adapters (uint)
 debug:Debug level (0=3Dnone,...,16=3Dall) (int)
