> Subject: [PATCH v2 4/4] net/iavf: add support for runtime queue
> reconfiguration
>
> Unlike the i40e driver, the iavf driver does not advertise support for runtime
> reconfiguration, meaning that application using the same hardware may get
> different behaviour when using a PF vs a VF. On testing with a 40G NIC, the
> only blocker to reconfiguring an RX queue on the fly is the fact that this
> support is not advertised by the driver.
>
> Add support for runtime reconfig by reporting it in the device info flags.
