29 * This module is intended to manage multicast addresses, address override,
30 * and promiscuous mode on GEnesis and Yukon adapters.

32 * Address Layout:
33 * port address: physical MAC address
34 * 1st exact match: logical MAC address (GEnesis only)
35 * 2nd exact match: RLMT multicast (GEnesis only)
36 * exact match 3-13: OS-specific multicasts (GEnesis only)

113 * SK_INIT_DATA
114 * ============
115 *
116 * This routine clears the multicast tables and resets promiscuous mode.
117 * Some entries are reserved for the "logical MAC address", the
118 * SK-RLMT multicast address, and the BPDU multicast address.
119 *
120 *
121 * SK_INIT_IO
122 * ==========
123 *
124 * All permanent MAC addresses are read from EPROM.
125 * If the current MAC addresses are not already set in software,
126 * they are set to the values of the permanent addresses.
127 * The current addresses are written to the corresponding MAC.
