Subject: ethdev: reset device and interrupt pointers on release
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2c65898b4813baba7aadce57b68212d5af82a2fd;p=dpdk.git

ethdev: reset device and interrupt pointers on release

The pointers .device and .intr_handle were already reset by the helper
rte_eth_dev_pci_generic_remove().
It is now made part of rte_eth_dev_release_port().

It makes rte_eth_dev_pci_release() meaningless,
so it is replaced with a call to rte_eth_dev_release_port().
