Theoretically, source id check is not mandatory in the context we use VT-D here (i.e. non VM one, just multi-vector MSI support) Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>

Such interrupt remapping hardware is provided through Intel VT-D
|
|
technology. It's being used, currently, only for MSI/MSI-X
|
|
multi-vector support. If you have such PCIe device requiring
|
|
multi-vector support, you will need to enable this.
