    be2net: Support for OS2BMC. · 760c295e

    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.
