From dc89abe5a9382147e3b2e1f713d46b0a0f3cd0b2 Mon Sep 17 00:00:00 2001 From: Thomas Monjalon Date: Tue, 29 Sep 2020 01:14:11 +0200 Subject: [PATCH] net/af_packet: 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.
