I tried to implement serial io via EEPROM, referred to Linux driver,
then succeed in probing PHY and it seems work,
sis0: <SiS 900 10/100BaseTX> port 0xd400-0xd4ff mem 0xdfff9000-0xdfff9fff irq 11 at device 3.0 on pci0
sis0: Ethernet address: 00:07:95:c0:de:e2
miibus0: <MII bus> on sis0
rlphy0: <RTL8201L 10/100 media interface> on miibus0
rlphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
but it seems something is strange with multicast handling.
For example,
try to ping6 to all-node multicast such as
[sishost]# ping6 -c 2 ff02::1%sis0
PING6(56=40+8+8 bytes) fe80::207:95ff:fec0:dee2%sis0 --> ff02::1%sis0
16 bytes from fe80::207:95ff:fec0:dee2%sis0, icmp_seq=0 hlim=64 time=0.316 ms
16 bytes from fe80::204:76ff:fe6e:1f81%sis0, icmp_seq=0 hlim=64 time=0.769 ms(DUP!)
16 bytes from fe80::207:95ff:fec0:dee2%sis0, icmp_seq=1 hlim=64 time=0.21 ms

2 packets transmitted, 2 packets received, +1 duplicates, 0% packet loss
round-trip min/avg/max/std-dev = 0.210/0.432/0.769/0.242 ms
and tcpdump on same host,
[sishost]# tcpdump -i sis0

unknown packets are sent from sis.
This might be same problem discuss in freebsd-hackers@freebsd.org
several months ago.(Subject: Multicast problem with sis interface?)
