The latest version uses prov->cq for all RX packets, so
it's trivial to merge it with NAPI if we want: the relevant part
of the patch is:

 static void ipoib_ib_handle_wc(struct net_device *dev, struct ib_wc *wc)
 {
-       if (wc->wr_id & IPOIB_OP_RECV)
+       if (wc->wr_id & IPOIB_CM_OP_SRQ)
+               ipoib_cm_handle_rx_wc(dev, wc);
+       else if (wc->wr_id & IPOIB_OP_RECV)
                ipoib_ib_handle_rx_wc(dev, wc);
        else
                ipoib_ib_handle_tx_wc(dev, wc);


I haven't tested this combination yet.
