Subject: net/mlx5: fix Unix socket path
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=733bbf518f53fbc596b40a528dc73f69eea77ca0;p=dpdk.git

net/mlx5: fix Unix socket path

mlx_steering_dump_parser.py tool failed to dump flow due to socket file
name changed.

Change socket file name back to make it consistent.

Fixes: e4b7b8d082db ("common/mlx5: fix PCI driver name")
