You need to use the GLDv3 interfaces and do the following:
Implement a function that takes (void *arg, uint_t naddr, uint8_t
*addr) as arguments, and populates *addr with the value of MAC address
'naddr'.
Implement the get capability callback in your mac_callbacks
struct, as well as set the MC_GETCAPAB flag. The callback should when
bassed the MAC_CAPAB_MULTIFACTADDR capability return the number of
addresses and the function pointer to the above function.
Don't know if it's the best example, but
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/io/nxge/nxge_main.c#330
and
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/io/nxge/nxge_main.c#nxge_m_getcapab
provides an example of this.
