From d26e543891068254c4575567a31280be5881e49d Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Wed, 12 Dec 2018 12:39:56 -0700 Subject: [PATCH] vfio/pci: Remove PCIe Link Status emulation Now that the downstream port will virtually negotiate itself to the link status of the downstream device, we can remove this emulation. It's not clear that it was every terribly useful anyway. Tested-by: Geoffrey McRae Reviewed-by: Eric Auger Signed-off-by: Alex Williamson Reviewed-by: Michael S. Tsirkin Signed-off-by: Michael S.
