From 2c65898b4813baba7aadce57b68212d5af82a2fd Mon Sep 17 00:00:00 2001 From: Thomas Monjalon Date: Tue, 29 Sep 2020 01:14:09 +0200 Subject: [PATCH] ethdev: reset device and interrupt pointers on release The pointers .device and .intr_handle were already reset by the helper rte_eth_dev_pci_generic_remove(). It is now made part of rte_eth_dev_release_port(). It makes rte_eth_dev_pci_release() meaningless, so it is replaced with a call to rte_eth_dev_release_port().
