IPI's from the victim cpu are not handled in dev_cpu_callback. So these pending IPI's would be sent to the remote cpu only when NET_RX is scheduled on the victim cpu and since this trigger is unpredictable it would result in packet latencies on the remote cpu. This patch adds support to send the pending ipi's of victim cpu.
