Subject: [PATCH] net: Add option to disable fiber on M88E1111 PHY for PPC4xx
By defining CONFIG_M88E1111_DISABLE_FIBER boards can configure the
M88E1111 PYH to disable fiber. This is needed for an upcoming PPC460GT
based board, which has fiber/copper auto-selection enabled by default.
This doesn't seem to work. So we disable fiber in the PHY register.
