Most likely you need to update your switch FW.  You need Anafa2 FW
version 1.0 to negotiate a DDR link with ConnectX.

BTW what firmware version do you have on your HCAs?  You probably want
to update to 2.0.156 (the mlx4 driver won't work with 2.0.158 for a
day or two still) so that you don't have to monkey around with
hard-coding your switch ports to DDR only.
