be2net: Support for OS2BMC.
OS2BMC feature will allow the server to communicate with the on-board BMC/idrac (Baseboard Management Controller) over the LOM via standard Ethernet. When OS2BMC feature is enabled, the LOM will filter traffic coming from the host. If the destination MAC address matches the iDRAC MAC address, it will forward the packet to the NC-SI side band interface for iDRAC processing. Otherwise, it would send it out on the wire to the external network. Broadcast and multicast packets are sent on the side-band NC-SI channel and on the wire as well. Some of the packet filters are not supported in the NIC and hence driver will identify such packets and will hint the NIC to send those packets to the BMC. This is done by duplicating packets on the management ring. Packets are sent to the management ring, by setting mgmt bit in the wrb header. The NIC will forward the packets on the management ring to the BMC through the side-band NC-SI channel.
