This patch makes the following changes to the static trace: 1. Adds the decoding of TID RDMA READ packets in IB header trace; 2. Tracks qpriv->s_flags and iow_flags in qpsleepwakeup trace; 3. Adds a new event to track RC ACK receiving; 4. Adds trace events for various stages of the TID RDMA READ protocol. These events provide a fine-grained control for monitoring and debugging the hfi1 driver in the filed.
