RDMA/rxe: Set sys_image_guid to be aligned with HW IB devices
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") Link: https://lore.kernel.org/r/20200323112800.1444784-1-leon@kernel.org Signed-off-by: Zhu Yanjun <yanjunz@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
