Subject: [dpdk-dev] [PATCH v1 1/4] net/dpaa: release port upon close
Date: Mon, 28 Sep 2020 14:27:10 +0530
Message-ID: <20200928085713.13560-2-sachin.saxena@oss.nxp.com> (raw)
In-Reply-To: <20200928085713.13560-1-sachin.saxena@oss.nxp.com>

From: Sachin Saxena <sachin.saxena@oss.nxp.com>

With removal of old close behavior, the private
port resources must be released in the .dev_close callback.
Freeing of port private resources is moved from
the ".remove(device)" to the ".dev_close(port)" operation
