* RDS/IW+IB: Set the RDS_LL_SEND_FULL bit when we're throttled.Steve Wise2009-04-091-1/+1
| | | | | | | | | | The RDS_LL_SEND_FULL bit should be set when we stop transmitted due to flow control. Otherwise the send worker will keep trying as opposed to sleeping until we unthrottle. Saves CPU. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
