This patch adds support for 1000BASE-X to functions "miiphy_speed ()" and "miiphy_duplex()". It also adds function "miiphy_is_1000base_x ()", which returns non-zero iff the PHY registers are configured for 1000BASE-X. The "mii info" command is modified to distinguish between 1000BASE-T and -X. Signed-off-by: Larry Johnson <lrj@acm.org> Signed-off-by: Ben Warren <bwarren@qstreams.com>
