Using 4.4-rc5+ [1] and **not** applying any of the patches I sent today,
I noted that RoCE passive side isn't working (rdma-cm, ibv_rc_pingpong
works).
I have two nodes in ConnectX3 VPI config (port1 IB and port2 Eth), the
one with the 4.4-rc5 kernel can act as both (rping) client/server for
IB links but only (rping) client for RoCE.
I tried both inter-node and loopback runs, in all cases, the client
side getsCM
reject with reason 28, see [2], tried both iser and rping. Eth (ICMP,
TCP) works OK.
OK, small progress, when the force Eth link type on my IB port (using
mlx4 sysfs), things work.
You should be able to reproduce it on your non-VPI systems the other way
around, by
forcing IB link type on one of the Eth ports and see the failure.
I Saw the same behavior with both 4.4-rc2 and 4.4-rc5
