This looks like an ARP issue across your IPoIB interfaces.
Please see section 6 of the uDAPL OFED BKM.

6. Multi IB port configuration, IPoIB arp reply issues
When two interfaces running one interface may reply to an ARP
directed to the other interface on the system. The following
configuration will cause the interfaces to ignore ARP requests if
not specifically for their IP address.
Add the following lines to /etc/sysctl.conf
net.ipv4.conf.all.arp_ignore=1
net.ipv4.conf.ib0.arp_ignore=1
net.ipv4.conf.ib1.arp_ignore=1
or use sysctl:
sysctl -w net.ipv4.conf.all.arp_ignore=1
sysctl -w net.ipv4.conf.ib0.arp_ignore=1
sysctl -w net.ipv4.conf.ib1.arp_ignore=1

Subject: [ofa-general] Multiports single HCA uDAPL program problem
Hi All,
I am kind of noob on IB and uDAPL program. Currently, I am trying to
write a program with multirail that utilizes 2 ports on a
single Mallenox
ConnectX HCA on both nodes.
OFED1.3 has been installed on a SUSE 10.3 linux system.
The current problem is that IB connection via uDAPL are very unstable,
and sometime the connection can't be established.
Error message is usually like:
20350 Server waiting for connect request on port 45248
accept: ERR dev(0x61d0e0!=0x61d0e0) or port mismatch(1!=2)
20350 Error dat_cr_accept: DAT_INTERNAL_ERROR
20350 Error connect_ep: DAT_INTERNAL_ERROR
The status of both port are active:
hca_id: mlx4_0
fw_ver: 2.3.000
node_guid: 0003:ba00:0100:702c
sys_image_guid: 0003:ba00:0100:702f
vendor_id: 0x02c9
vendor_part_id: 25418
hw_ver: 0xA0
board_id: SUN0070000001
phys_port_cnt: 2
port: 1
state: PORT_ACTIVE (4)
max_mtu: 2048 (4)
active_mtu: 2048 (4)
sm_lid: 10
port_lid: 8
port_lmc: 0x00
port: 2
state: PORT_ACTIVE (4)
max_mtu: 2048 (4)
active_mtu: 2048 (4)
sm_lid: 10
port_lid: 9
port_lmc: 0x00
I haven't done any specific configuration for multi-port. I assume that
OFED1.3 can do it automatically.
Would please any one help me on this?
Regards,
Jie
