The CX4 card cannot cope with a context with PE=0 due to a hardware limitation, resulting in: [ 34.166577] command failed, status limits exceeded(0x8), syndrome 0x5a7939 [ 34.166580] mlx5_core 0000:01:00.1: Failed allocating uar, aborting Since the kernel API allocates a default context very early during device init that will almost certainly get Process Element ID 0 there is no easy way for us to extend the API to allow the Mellanox to inform us of this limitation ahead of time. Instead, work around the issue by extending the XSL structure to include a minimum PE to allocate. Although the bug is not in the XSL, it is the easiest place to work around this limitation given that the CX4 is currently the only card that uses an XSL.
