Hello, I have Linux 4.10.0 stable running on two at91 ARM machines. I have rdma-core 13 installed on both. "rxe_cfg status" shows normal information, e.g.: Name Link Driver Speed NMTU IPv4_addr RDEV RMTU eth0 yes macb 1500 192.168.0.12 rxe0 1024 (3) "ibv_devinfo" likewise shows normal information, e.g.: hca_id: rxe0 transport: InfiniBand (0) fw_ver: 0.0.0 node_guid: 1034:56ff:fe84:1952 sys_image_guid: 0000:0000:0000:0000 vendor_id: 0x0000 vendor_part_id: 0 hw_ver: 0x0 phys_port_cnt: 1 port: 1 state: PORT_ACTIVE (4) max_mtu: 4096 (5) active_mtu: 1024 (3) sm_lid: 0 port_lid: 0 port_lmc: 0x00 link_layer: Ethernet Every communication tool I have tried hangs after printing remote address information. No errors are printed or logged in dmesg. Example: ## This is system A # ibv_rc_pingpong -d rxe0 -g 1 -i 1 192.168.0.12 local address: LID 0x0000, QPN 0x000011, PSN 0xd1d8a8, GID ::ffff:192.168.0.11 remote address: LID 0x0000, QPN 0x000011, PSN 0xc55eed, GID ::ffff:192.168.0.12 ## This is system B # ibv_rc_pingpong -d rxe0 -g 1 -i 1 local address: LID 0x0000, QPN 0x000011, PSN 0xc55eed, GID ::ffff:192.168.0.12 remote address: LID 0x0000, QPN 0x000011, PSN 0xd1d8a8, GID ::ffff:192.168.0.11 If it makes a difference, I have a 10/100 switch connected at the moment. I am merely trying to verify functionality, not reach high speeds. I have found previous message(s) with similar problems on mailing lists and online but no resolution to date. Is there any configuration option I might have missed? I have no iptables firewall, and have even tried directly connecting the two systems instead of using the Ethernet switch.
