Hardware triggers an interrupt for events like PN wrap to zero,
PN crosses set threshold. This interrupt is received
by the MCS_AF. MCS AF then finds the PF/VF to which SA is mapped
and notifies them using mcs_intr_notify mbox message.

PF/VF using mcs_intr_cfg mbox can configure the list
of interrupts for which they want to receive the
notification from AF.
