The Marvell 88E6161 generates an interrupt when link status of the base interface is changed.
The interrupt handler (IPMC or Payload) will read the link status of the Base Ethernet via MDIO
(SMI) interface, and enable/disable the corresponding physical link to the CaveCreek's Ethernet
device. The payloads Ethernet driver will detect the link change and can propagate this
information. MDIO Interface can be implemented as Bit Bang Interface or FPGA can handle the
Interface.
