Subject: net/pfe: release port upon close
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=57803c5ef5a1d067330b0dd7e314149e4ef3a3c3;p=dpdk.git

net/pfe: release port upon close

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
