From 3ca5f4c06892fdd1c7a4587af4d92550a170ef37 Mon Sep 17 00:00:00 2001 From: Easwar Hariharan Date: Mon, 25 Jul 2016 13:39:51 -0700 Subject: [PATCH] IB/hfi1: Disable external device configuration requests QSFP CDR enablement is now controlled by determining power class and the configuration file. We disable the DC 8051 from requesting enablement or disabling of TX and RX CDRs by removing the code that allowed the DC 8051 to request changes.
