Subject: net/bonding: release port upon close
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=171875d0678c5ee8f8ce01eb887aa94294611462;p=dpdk.git

net/bonding: release port upon close

The flag RTE_ETH_DEV_CLOSE_REMOVE is set so all port resources
can be freed by rte_eth_dev_close().

Freeing of private port resources is moved
from the ".remove(device)" to the ".dev_close(port)" operation.
