On the SKY-8101 platform, dual NIC chips (two Intel i210 Ethernet controllers) are connected
to the BMC via one NC-SI interface (see the figure below).
Every time the BMC starts up, it scans the LINK condition of both management ports
(MGMT1 and MGMT2, see Figure 3).
If both ports have a link, users can reach BMC via IOL in different networking domain.
