My understand it could happen from the comments under
static void ipoib_cm_start_rx_drain()
{
/*
* QPs on flush list are error state. This way, a "flush
* error" WC will be immediately generated for each WR we post.
*/
p = list_entry(priv->cm.rx_flush_list.next, typeof(*p), list);
if (ib_post_send(p->qp, &ipoib_cm_rx_drain_wr, &bad_wr))
ipoib_warn(priv, "failed to post drain wr\n");
...
}
Eli, Please clarify here.
Thanks
