Birger Koblitz 483dd5f36f ixgbe: Add 10G-BX support
Add support for 10G-BX modules, i.e. 10GBit Ethernet over a single strand
Single-Mode fiber.
The initialization of a 10G-BX SFP+ is the same as for a 10G SX/LX module,
and is identified according to SFF-8472 table 5-3, footnote 3 by the
10G Ethernet Compliance Codes field being empty, the Nominal Bit
Rate being compatible with 12.5GBit, and the module being a fiber module
with a Single Mode fiber link length.

This was tested using a Lightron WSPXG-HS3LC-IEA 1270/1330nm 10km
transceiver:
