From: Liron Himi Date: Mon, 5 Aug 2019 10:16:56 +0000 (+0300) Subject: net/mvpp2: remove resources when port is closed X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=696202ca539612c579494dd536eb328bd595b05c;p=dpdk.git net/mvpp2: remove resources when port is closed Since 18.11, it is suggested that driver should release all its private resources at the dev_close routine. So all resources previously released in remove routine are now released at the dev_close routine, and the dev_close routine will be called in driver remove routine in order to support removing a device without closing its ports. Above behavior changes are supported by setting RTE_ETH_DEV_CLOSE_REMOVE flag during probe stage.
