Ernesto Castellotti 1b43e0d20f ixgbe: Add 1000BASE-BX support
Added support for 1000BASE-BX, i.e. Gigabit Ethernet over single strand
of single-mode fiber.
The initialization of a 1000BASE-BX SFP is the same as 1000BASE-SX/LX
with the only difference that the Bit Rate Nominal Value must be
checked to make sure it is a Gigabit Ethernet transceiver, as described
by the SFF-8472 specification.

This was tested with the FS.com SFP-GE-BX 1310/1490nm 10km transceiver:
