I certainly do Jack!  LOL.

However, would it be possible to please make this a kenv tunable in
the driver?  Its kinda stupid I have to recompile to add a SFP.  It
can certainly be an unsupported feature by you.

Patch attached.  Tested with CURRENT driver on a 7.2-amd64-release
machine.  If you set the tunable to 1, ixgbe loads without issue.  If
you leave it to zero (default), it will not attach to unsupported
SFPs.

I also added DEBUGOUT6 since it was missing and caused a compilation
failure when I turned on in-driver debugging.

What do you think?
