Add support for keepalive functionality. By default, the keepalive is off and can be enabled/disabled only at init time. For eg: To enable keepalive feature. 'ovs-vsctl --no-wait set Open_vSwitch . other_config:enable-keepalive=true' To set timer interval of 500ms for monitoring packet processing cores; 'ovs-vsctl --no-wait set Open_vSwitch . \ other_config:keepalive-interval="500" To set shared memory block name where the events shall be updated 'ovs-vsctl --no-wait set Open_vSwitch . other_config:keepalive-shm-name="/ovs_keepalive_shm_name"' Signed-off-by: Bhanuprakash Bodireddy <bhanuprakash.bodireddy@intel.com> --- vswitchd/vswitch.xml | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+)
