From a1f57a29a4a922cb799bc3b828ca19e97b02a1e5 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 9 Sep 2013 17:14:14 -0600 Subject: [PATCH] lspci: Decode PCIe LnkCtl "Read Completion Boundary" for PCIe-to-PCI bridges The PCIe spec (r3.0, Table 7-16) says the Read Completion Boundary is valid for Root Ports, Endpoints, and Bridges. I only added decoding for PCIe-to- PCI/PCI-X bridges because the RCB of a Bridge indicates the RCB of the upstream Root Port, so I don't think it makes sense for PCI-to-PCIe bridges.
