> up/down
> 
> In this scenario, kernel PF + DPDK VF, when PF finds the link state changes,
> up -> down or down -> up, it will send a message to VF by mailbox. This link
> state change may be triggered by PHY disconnection/reconnection,
> configuration like *ifconfig down/up* or interface parameter, like MTU,
> change.
> This patch enables the support of the mailbox interruption, so VF can receive
> the message of link up/down.
> After VF receives this message, VF port need to be reset to recover. So the
> handler of this message registers a reset callback to let APP reset the VF port.
