You still don't have this right. :(
Like this:
diff --git a/drivers/infiniband/hw/cxgb4/cm.c b/drivers/infiniband/hw/cxgb4/cm.c index 5e153f6..3c55e88 100644 --- a/drivers/infiniband/hw/cxgb4/cm.c +++ b/drivers/infiniband/hw/cxgb4/cm.c @@ -457,6 +457,8 @@ static void send_flowc(struct c4iw_ep *ep, struct sk_buff *skb) int i;

flowc->op_to_nparams = cpu_to_be32(FW_WR_OP(FW_FLOWC_WR) |
