Your devices are not showing up because the driver is failing to load.
Erroe -15 is IXGBE_ERR_RESET_FAILED, so it seems there is either
something wrong with your cards of you are hitting a driver bug.
You should probably turn on dynamic debugging for the ixgbe module and
see if you can figure out what might be going wrong. A guide for using
dynamic debugging can be found in Documentation/dynamic-debug-howto.txt.
