+Subject: [PATCH] PCI: brcmstb: Advertise MSI-X support
+
+Although the BRCMSTB PCIe interface doesn't technically support the
+MSI-X spec, in practise it seems to work provided no more than 32
+MSI-Xs are required. Add the required flag to the driver to allow
+experimentation with devices that demand MSI-X support.
