[dpdk-dev] [PATCH v1 1/4] net/dpaa: release port upon close

[Sachin Saxena (OSS)]

From: Sachin Saxena <sachin.sax...@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
