Sometimes the MII is not used at all - for example, when the controller is connected to a switch with a fixed speed, and the MDC/MDIO signal are used for something else. Allow to set a fixed speed in the FEC driver without relying on the autonegotiation. Signed-off-by: Stefano Babic <sbabic@denx.de> --- The use case is the FEC connected to a Switch without using MDIO / MDC. The FEC has no way to get the speed. drivers/net/fec_mxc.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
