The change above needs to be:
if (!test_bit(IPOIB_MCAST_FLAG_ATTACHED, &priv->broadcast->flags)) {
if (!test_bit(IPOIB_MCAST_FLAG_BUSY, &priv->broadcast->flags))
ipoib_mcast_join(dev, priv->broadcast, 0);
return;
}
Or additional join requests will start before we've finished joining the
broadcast group.
