> Hi, Thomas
>
> *The commit log:*
> In secondary process, rte_eth_dev_close() doesn't clear eth_dev->data.
> If calling rte_dev_remove() after rte_eth_dev_close(), in
> rte_eth_dev_pci_generic_remove()
> function, the released eth device still can be found by its name in
> shared memory.
> As a result, the eth device will be released repeatedly. The state of
> the eth device
> is modified to RTE_ETH_DEV_UNUSED after rte_eth_dev_close(). So this
> state can
> be used to avoid this problem.
>
> Is that will be more clear?
Yes, that's clear (at least for me).

Yes. One small change, I think "which" should be "it".
> Hope for your reply. Thanks.
