            Bug ID: 887
           Summary: mlx5: cannot probe ConnectX-6 Dx if socket-limit is
                    too small on NUMA socket 0
           Product: DPDK
           Version: 21.08
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: sunnylandh@gmail.com
  Target Milestone: ---

Our client has a ConnectX-6 Dx Ethernet adapter, installed on a PCI slot
belonging to NUMA socket 1.
When DPDK is initialized with flags "--socket-limit 1,2048 -a c1:00.0", PCI
probe fails with this message:

EAL: No available 2048 kB hugepages reported
EAL: No free 2048 kB hugepages reported on node 0
EAL: No free 2048 kB hugepages reported on node 1
EAL: No available 2048 kB hugepages reported
mlx5_net: probe of PCI device 0000:c1:00.0 aborted after encountering an er=
ror:
Cannot allocate memory
mlx5_common: Failed to load driver mlx5_eth
EAL: Requested device 0000:c1:00.0 cannot be used
EAL: Bus (pci) probe failed.

I suspect somewhere in the driver is trying to allocate certain objects on =
NUMA
socket 0, but I don't know which.
It should be changed to allow allocation on any NUMA socket.
