i40e refuses to load with Fiberxon 10G SFP+ on X710: no allow-unsupported-SFP option
The poster's Intel Ethernet Converged Network Adapter X710 would not come up with third-party Fiberxon 10G SFP+ modules: the i40e driver, version 1.2.48, refused to initialise and reported "The driver failed to load because unsupported module type was detected." They asked how to switch on an option in i40e that allows unsupported SFP modules so that the Fiberxon optics could be used with the adapter.

Stick to the optics listed in Intel's X710 product brief. As far as I know, the i40e driver doesn't offer any option to allow unsupported SFP modules.
Intel documents the
allow_unsupported_sfpmodule parameter for ixgbe here: https://www.intel.com/content/www/us/en/support/articles/000005528/ethernet-products.html - worth reading before recoding the module, because newer in-tree drivers still honour it.
