Robert Hancock 1887023a5e net: phy: marvell: add special handling of Finisar modules with 88E1111
The Finisar FCLF8520P2BTL 1000BaseT SFP module uses a Marvel 88E1111 PHY
with a modified PHY ID. Add support for this ID using the 88E1111
methods.

By default these modules do not have 1000BaseX auto-negotiation enabled,
which is not generally desirable with Linux networking drivers. Add
handling to enable 1000BaseX auto-negotiation when these modules are
used in 1000BaseX mode. Also, some special handling is required to ensure
that 1000BaseT auto-negotiation is enabled properly when desired.

Based on existing handling in the AMD xgbe driver and the information in
the Finisar FAQ:
