Extended OpenFlow monitoring support
* OpenFlow 1.3 with ONF extensions
* OpenFlow 1.4+ as defined in OpenFlow specification 1.4+.
ONF extensions are similar to Nicira extensions except for onf_flow_monitor_request{}
where out_port is defined as 32-bit number OF(1.1) number, oxm match formats are
used in update and request messages.
Flow monitoring support in 1.4+ is slightly different from Nicira and ONF
extensions.
* More flow monitoring flags are defined.
* Monitor add/modify/delete command is introduced in flow_monitor
request message.
* Addition of out_group as part of flow_monitor request message
Description of changes:
1. Generate ofp-msgs.inc to be able to support 1.3, 1.4+ flow Monitoring messages.
include/openvswitch/ofp-msgs.h
2. Modify openflow header files with protocol specific headers.
include/openflow/openflow-1.3.h
include/openflow/openflow-1.4.h
3. Modify OvS abstraction of openflow headers. ofp-monitor.h leverages enums
from on nicira extensions for creating protocol abstraction headers. OF(1.4+)
enums are superset of nicira extensions.
include/openvswitch/ofp-monitor.h
4. Changes to these files reflect encoding and decoding of new protocol messages.
lib/ofp-monitor.c
5. Changes to modules using ofp-monitor APIs. Most of the changes here are to
migrate enums from nicira to OF 1.4+ versions.
ofproto/connmgr.c
ofproto/connmgr.h
ofproto/ofproto-provider.h
ofproto/ofproto.c
6. Extended protocol decoding tests to verify all protocol versions
FLOW_MONITOR_CANCEL
FLOW_MONITOR_PAUSED
FLOW_MONITOR_RESUMED
FLOW_MONITOR request
FLOW_MONITOR reply
tests/ofp-print.at
7. Modify flow monitoring tests to be able executed by all protocol versions.
