Jon Paul Maloy 2cdf3918e4 tipc: eliminate unnecessary call to broadcast ack function ... The unicast packet header contains a broadcast acknowledge sequence number, that may need to be conveyed to the broadcast link for proper treatment. Currently, the function tipc_rcv(), which is on the most critical data path, calls the function tipc_bclink_acknowledge() to have this done. This call is made for each received packet, and results in the unconditional grabbing of the broadcast link spinlock. This is unnecessary, since we can see directly from tipc_rcv() if the acknowledged number differs from what has been previously acked from the node in question. In the vast majority of cases the numbers won't differ, and there is nothing to update. We now make the call to tipc_bclink_acknowledge() conditional to that the two ack values differ.
