From: Rastislav Cernay Date: Tue, 27 Aug 2019 20:37:16 +0000 (+0200) Subject: net/nfb: remove resources when port is closed X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=f1d59d3fc8adc8338c010f0ab742a8abb761c4c8;p=dpdk.git net/nfb: remove resources when port is closed The rte_eth_dev_close() function now handles freeing resources for devices (e.g., mac_addrs). To conform with the new close() behaviour we are asserting the RTE_ETH_DEV_CLOSE_REMOVE flag so that rte_eth_dev_close() releases all device level dynamic memory.
