This series of patches implements the multi-threading bfd/cfm in
ofproto-dpif-monitor module. This module is in charge of the
execution of periodic functions (like bfd_run, cfm_run,
bfd_send_packets).
With the ofproto-dpif-monitor module, the openvswitch can easily
support more than 10,000 interface monitor sessions.
Patches 1-6:
The implementation of ofproto-dpif-monitor module.
Patches 7-10:
The optimization of ofproto-dpif-monitor module.
Alex Wang (10):
ofproto-dpif: Move send_packet() to ofproto-dpif-xlate module.
ofproto-dpif: Make stats update thread safe.
tests: Remove the unit test for "ovs-appctl coverage/show".
timeval: Wake up all threads when time is warped.
ofproto-dpif-monitor: Add ofproto-dpif-monitor module.
ofproto-dpif-monitor: Run ofproto-dpif-monitor in a thread.
heap: Change type of "priority" in "struct heap".
bfd: Add bfd_wake_time() function.
cfm: Add cfm_wake_time() function.
ofproto-dpif-monitor: Use heap to order the mport wakeup time.
