From 6dc5939fc78a55caddc5bfca756ee0c2d35d3208 Mon Sep 17 00:00:00 2001 From: Seema Khowala Date: Tue, 10 Jul 2018 13:29:14 -0700 Subject: nvlink: t19x: Remove 25GBPS speed support Based on A01 Silicon Characterization, we cannot meet Nvlink POR speeds of 25G across 100% bin and hence 25GBPS is defeatured.
