[dpdk-dev] [PATCH v2 2/2] igb: VF supports mailbox interruption for PF link 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.
