Subject: net/bnx2x: release port upon close
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8f3aee84f3c29ecad85d6f9e9f141b1bfa1d98fe;p=dpdk.git

net/bnx2x: release port upon close

Set RTE_ETH_DEV_CLOSE_REMOVE upon probe so all the private resources
for the port can be freed by rte_eth_dev_close(). With this change the
private port resources are released in the .dev_close callback.
