[ Upstream commit d0ca2c35dd15a3d989955caec02beea02f735ee6 ]
The RXE driver doesn't set sys_image_guid and user space applications see zeros. This causes to pyverbs tests to fail with the following traceback, because the IBTA spec requires to have valid sys_image_guid.
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 74, in verify_device_attr assert attr.sys_image_guid != 0
In order to fix it, set sys_image_guid to be equal to node_guid.
Before: 5: rxe0: ... node_guid 5054:00ff:feaa:5363 sys_image_guid 0000:0000:0000:0000
After: 5: rxe0: ... node_guid 5054:00ff:feaa:5363 sys_image_guid 5054:00ff:feaa:5363
