Thanks for the reply Jack,
The code for the 82599 is specific in that it checks for (and allows to
be used) ONLY Intel SFP+'s. The 82598 is a little more flexible in that
it supports 4 vendors (including Finisar). Any idea why 4 SFP+ vendors
are supported on the 82598, but not the 82599?
Also, the very existance of a definition for
IXGBE_DEVICE_CAPS_ALLOW_ANY_SFP (and code to check it) implies the
ability of the 82599 to be able to be configured to support "any" SFP,
although I can't find any reference to the bit or capability in the
82599 datasheet? Is that a possible "future" feature?
Lastly (for now), can support for an additional SFP+ (like the Finisar)
be */added /*to the 82599 driver or is there something that would
