I tried to install rdma-core from AUR and then executed:
sudo modprobe rdma_rxe
sudo rdma link add rxe0 type rxe netdev wlp60s0
then ibstat shows:
CA 'rxe0'
CA type:
Number of ports: 1
Firmware version:
Hardware version:
Node GUID: 0x4a51c5fffef6e159
System image GUID: 0x4a51c5fffef6e159
Port 1:
State: Active
Physical state: LinkUp
Rate: 2.5
Base lid: 0
LMC: 0
SM lid: 0
Capability mask: 0x00010000
Port GUID: 0x4a51c5fffef6e159
Link layer: Ethernet
But launching any example I always get an error by call of: ibv_modify_qp
with an attempt to modify QP state to RTR. The type of the error is EINVAL.
I believe I miss something very obvious.

I've got the answer through: linux-rdma (at) vger.kernel.org
The problem was with an IPv6 address. So I did:
ipv6calc --in prefix+mac fe80:: XX:XX:XX:XX:XX:XX
where the XX:XX:XX:XX:XX:XX is a correspondent mac address
and then:
sudo ip addr add dev <dev> fe80::ZZZZ:ZZZZ:ZZZZ:ZZZZ/64
which added the needed address
Solved!
