From: Ido Goshen <i...@cgstowernetworks.com>

10BASE-T SFP+ copper transceivers become cheaper and popular
So far those were blocked by ixgbe as “unsupported”.
e.g.
        eth_ixgbe_dev_init(): Unsupported SFP+ Module
        eth_ixgbe_dev_init(): Hardware Initialization Failure: -19
        EAL: Requested device 0000:0a:00.0 cannot be used

This patch expands the usage of allow_unsupported_sfp to be more general
and makes ixgbe more tolerant to unknown SFPs
