Perhaps there is something funky with rping, it works fine in simpler cases:

$ rdma link show
link siw0/1 state ACTIVE physical_state LINK_UP netdev enp0s31f6 
$ sudo rmmod ib_uverbs
$ build/bin/ibv_devinfo
hca_id:	siw0
	transport:			iWARP (1)
	fw_ver:				0.0.0
	node_guid:			7686:e2ff:fe28:63fc
	sys_image_guid:			7486:e228:63fc:0000
	vendor_id:			0x626d74
	vendor_part_id:			1
	hw_ver:				0x0
	phys_port_cnt:			1
		port:	1
			state:			PORT_ACTIVE (4)
			max_mtu:		1024 (3)
			active_mtu:		1024 (3)
			sm_lid:			0
			port_lid:		0
			port_lmc:		0x00
			link_layer:		Ethernet
$ lsmod | grep -i uverb
ib_uverbs             163840  0
ib_core               393216  2 ib_uverbs,siw
