NC-SI (Network Controller Sideband Interface) enables a BMC to manage a set of NICs on a system. This model takes the simplest approach and reverses the NC-SI packets to pretend a NIC is present and exercise the Linux driver. The NCSI header file <ncsi-pkt.h> comes from mainline Linux and was untabified.
