From 8ad3c8cfcf002557a8302156b79be4c54d4e22d1 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 9 Sep 2013 17:14:21 -0600 Subject: [PATCH] lspci: Drop PCIe LnkCtl "Retrain Link" decoding Per PCIe spec r3.0, Table 7-16, the Retrain Link bit is writable but always returns 0 when read, so decoding it gives no useful information.
