> The data resource in struct rte_eth_dev is cleared and points to NULL when

>
> If the DCF representor port is closed after the DCF port is closed, a
> segmentation fault occurs because the representor port accesses the data
> resource released by the DCF port.

> This patch fixes this issue by synchronizing the state of DCF ports and
> representor ports to the peer in real time when their state changes.
