Perhaps, the behavior depends on a system and the setting of the BIOS.
My Thinkpad X61 drops the link when I suspend with zzz command without my
change.

I'm sorry. My proposal is:

    0) Add the following definitions into net/if.h for the capability and
       enabled flag.

#define IFCAP_WOL_UCAST         0x080000 /* wake on any unicast frame */
#define IFCAP_WOL_MCAST         0x100000 /* wake on any multicast frame */
#define IFCAP_WOL_MAGIC         0x200000 /* wake on any Magic Packet */

#define IFCAP_WOL       (IFCAP_WOL_UCAST | IFCAP_WOL_MCAST | IFCAP_WOL_MAGIC)

    1) Add [-]wol, [-]wol_ucast, [-]wol_mcast and [-]wol_magic flags into
       ifconfig(8).
