From 39ae757770b3fe54fdd3e1e9656aabc72abc1e26 Mon Sep 17 00:00:00 2001 From: Suanming Mou Date: Sun, 24 Jan 2021 19:02:03 +0800 Subject: [PATCH] net/mlx5: fix multi-process port ID The device port_id is used for inter-process communication and must be the same both for primary and secondary process This IPC port_id was configured with the invalid temporary value in port spawn routine. This temporary value was used by the function rte_eth_dev_get_port_by_name() to check whether the port exists. This commit corrects the mp port_id with rte_eth_dev port_id.
