[ 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
Fixes: 8700e3e7c485 ("Soft RoCE driver")
