Tom Lendacky 03ea9ba5fd net: amd-xgbe: Fix logic around active and passive cables
[ Upstream commit 4998006c73afe44e2f639d55bd331c6c26eb039f ]

SFP+ active and passive cables are copper cables with fixed SFP+ end
connectors. Due to a misinterpretation of this, SFP+ active cables could
end up not being recognized, causing the driver to fail to establish a
connection.

Introduce a new enum in SFP+ cable types, XGBE_SFP_CABLE_FIBER, that is
the default cable type, and handle active and passive cables when they are
specifically detected.
