Subject: [PATCH 337/634] 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.
