IIRC (for example):
Bridge sis0 and sis1,

Ipfw add queue 1 from any to (destination network/24)
Ipfw queue 1 config weight 5 pipe 1 mask dst-ip 0x000000ff
Ipfw pipe 1 config bw 1024Kbit/s

Ipfw add queue 2 from (source network/24) to any
Ipfw queue 2 config weight 5 pipe 2 mask src-ip 0x000000ff
Ipfw pipe 2 config bw 1024Kbit/s

Somebody correct me if I'm wrong...

Adapt mask and dst/src network where needed.

Kind Regards,

J.
