> Subject: [PATCH v2] net/ice: fix data path corrupt on secondary process
>
> The rte_eth_devices array is not in share memory, it should not be referenced by
> ice_adapter which is shared by primary and secondary.
> Any process set ice_adapter->eth_dev will corrupt another process'
> context.
>
> The patch removed the field "eth_dev" from ice_adapter.
> Now, when the data paths try to access the rte_eth_dev_data instance, they
> should replace adapter->eth_dev->data with adapter->pf.dev_data.
