Okay, I am using the following group:

group_id=88,type=select,selection_method=hash,fields=ip_dst,bucket=bucket_id:0,actions=set_field:00:50:56:82:c8:03->eth_dst,set_field:00:50:56:82:cd:d3->eth_src,output:1,bucket=bucket_id:1,actions=set_field:00:50:56:82:89:d5->eth_dst,set_field:00:50:56:82:f7:c0->eth_src,output:2

I am certainly sure that there are different IP destinations (they are
randomly generated in a /16 network). However, still just one bucket is
matched:

---
root at M-OF-Core:~# ovs-ofctl -O OpenFlow15 dump-group-stats br0
OFPST_GROUP reply (OF1.5) (xid=0x2):
 group_id=88,duration=498.390s,ref_count=1,packet_count=636881,byte_count=262778258,bucket0:packet_count=636881,byte_count=262778258,bucket1:packet_count=0,byte_count=0
---

Any ideas?

Thanks and best regards
Daniel
