Some devices have problems with Transaction Layer Packets with the Relaxed
Ordering Attribute set. This patch set adds a new PCIe Device Flag,
PCI_DEV_FLAGS_NO_RELAXED_ORDERING, a set of PCI Quirks to catch some known
devices with Relaxed Ordering issues, and a use of this new flag by the
cxgb4 driver to avoid using Relaxed Ordering with problematic Root Complex
Ports.
It's been years since I've submitted kernel.org patches, I appolgise for the
almost certain submission errors.

PCI: Add new PCIe Fabric End Node flag,
PCI_DEV_FLAGS_NO_RELAXED_ORDERING
net/cxgb4: Use new PCI_DEV_FLAGS_NO_RELAXED_ORDERING flag
