Hello all,

We have several platforms based on Intel's C3000 series of SoCs that
have integrated ixgbe devices (X550EM) operating in the "Native SFI"
mode (the 0x15c4 device ID).

The first five patches in the series all fix issues relating to the ID
and setup of SFPs.

Patch 6 allows slow to boot SFPs (like some XGS-PON modules) to work.

Patch 7 enables 1G Cu to run with a warning, similar to other
unofficially supported modules covered by the allow_unsupported_sfp
flag.  Currently we use this for g.Fast modules, but other modules that
enumerate as 1G Cu may also benefit.

Since all of my testing was done on a C3000 platform, and the ixgbe
driver now covers a large number of devices, any regression testing that
can be done on other ixgbe devices would be greatly appreciated.

Thanks,
Steve
