NAME
    AddMulticastAddress -- Enable an interface multicast address.

FUNCTION
    This command causes the device driver to enable multicast packet
    reception for the requested address.

IO REQUEST
    ios2_Command    - S2_ADDMULTICASTADDRESS.
    ios2_SrcAddr    - Multicast address to enable.

RESULTS
    ios2_Error      - Zero if successful; non-zero otherwise.
    ios2_WireError  - More specific error number.

NOTES
    Multicast addresses are added globally -- anyone using the device
    may receive packets as a result of any multicast address which has
    been added for the device.

    Since multicast addresses are not "bound" to a particular packet type,
    each enabled multicast address has an "enabled" count associated with
    it so that if two protocols add the same multicast address and later
    one removes it, it is still enabled until the second removes it.
