RDMA/rxe: Set default vendor ID
The RXE driver doesn't set vendor_id and user space applications see zeros. This causes to pyverbs tests to fail with the following traceback, because the expectation is to have valid vendor_id. Traceback (most recent call last): File "tests/test_device.py", line 51, in test_query_device self.verify_device_attr(attr) File "tests/test_device.py", line 77, in verify_device_attr assert attr.vendor_id != 0 In order to fix it, we will set vendor_id 0XFFFFFF, according to the IBTA v1.4 A3.3.1 VENDOR INFORMATION section. """ A vendor that produces a generic controller (i.e., one that supports a standard I/O protocol such as SRP), which does not have vendor specific device drivers, may use the value of 0xFFFFFF in the VendorID field.
