From 1a7fa562fb5216386616b18b626fb9f21593bc05 Mon Sep 17 00:00:00 2001 From: Thomas Monjalon Date: Tue, 29 Sep 2020 01:14:19 +0200 Subject: [PATCH] net/failsafe: release port upon close The flag RTE_ETH_DEV_CLOSE_REMOVE is set so all port resources can be freed by rte_eth_dev_close(). Freeing of private port resources is moved from the ".remove(device)" to the ".dev_close(port)" operation.
