Subject: [PATCH net 0/2] net: ixgbe: Use new flag to disable Relaxed Ordering

The new flag PCI_DEV_FLAGS_NO_RELAXED_ORDERING has been added
to indicate that Relaxed Ordering Attributes (RO) should not
be used for Transaction Layer Packets (TLP) targeted toward
these affected Root Port, it will clear the bit4 in the PCIe
Device Control register, so the PCIe device drivers could
query PCIe configuration space to determine if it can send
TLPs to Root Port with the Relaxed Ordering Attributes set.

The ixgbe driver could use this flag to determine if it can
send TLPs to Root Port with the Relaxed Ordering Attributes set.
