# EXT-187 seems to have a lot of flaws.
# XXX the spec mentions ONFST_FLOW_MONITOR in some places.
# we assume it's same as ONFMP_FLOW_MONITOR.
# XXX the spec uses OFPP_NONE. we assume it means OFPP_ANY.
# XXX onf_flow_update_full.length is commented to be 24.
# but it needs to tell the actual length of instructions.
# we assume it's variable.
# XXX the spec seems confused between instructions and actions
# for onf_flow_update_full/ONFFMF_ACTIONS. we assume they all
# are instructions.
# XXX the spec does not define payload structures for any of
# ONFT_FLOW_MONITOR_CANCEL, ONFT_FLOW_MONITOR_PAUSED, or
# ONFT_FLOW_MONITOR_RESUMED. we assume they are same as NX.
# according to NX spec (OVS nicira-ext.h and ofp-msg.h):
# NXT_FLOW_MONITOR_CANCEL: a single u32 'id'.
# NXT_FLOW_MONITOR_PAUSED/RESUMED: empty payload
# (OF1.4 uses something different; OFPFMC_DELETE for CANCEL and
# OFPFME_ for PAUSED/RESUMED.)
# XXX onf_flow_monitor_request and onf_flow_update_full use
# match_len + oxm_fields instead of ofp_match. this pointless
# diverge from OF1.4 looks like a botch when updating from OF1.0.
# XXX the spec mentions "the current implementation of Open vSwitch"
# but, as of writing this, it doesn't have this extension implemented
# at all. we assume that it is about OF1.0 NX.
# XXX the spec mentions nx13_flow_monitor_request but i couldn't find
# it in OVS nicira-ext.h.
