I think it's done with client identifier for IB and it should be set
to the IPoIB hardware address (20 bytes) which
is QPN + GID. You should be able to determine this from:

ip addr show ib<n>

e.g.
ip addr show ib0
5: ib0: <BROADCAST,MULTICAST> mtu 2044 qdisc noop qlen 128
  link/[32] 00:0d:00:48:20:06:00:00:00:00:00:00:00:02:c9:03:00:00:14:91
brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff
ip addr show ib1
6: ib1: <BROADCAST,MULTICAST> mtu 2044 qdisc noop qlen 128
  link/[32] 00:0d:00:49:fe:80:00:00:00:00:00:00:00:02:c9:03:00:00:14:92
brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff
