From a4849fc157cdbe4fb68cfe37e7222697f003deb5 Mon Sep 17 00:00:00 2001 From: Chien Tung <chien.tin.tung@intel.com> Date: Wed, 8 Apr 2009 14:27:18 -0700 Subject: RDMA/nes: Add wide_ppm_offset parm for switch compatibility We have observed unstable link with a new BNT switch. Add wide_ppm_offset parameter to allow the user to control the clock ppm offset on the CX4 interface for better compatibility. Default is 100ppm, setting it to 1 will increase it to 300ppm. Change default SerDes1 reference clock to external source.
