Enumerator
CHANNEL_TRACKER_PEEK 

inquiring content, accumulating packet fragments

CHANNEL_TRACKER_PASS 

pass all the fragments of the current packet

CHANNEL_TRACKER_DROP 

drop all the fragments of the current packet

Function Documentation

◆ channelTracker_flushCurrent()

PfChannelResult channelTracker_flushCurrent ( ChannelStateTracker *  t,
BOOL  first,
BOOL  last,
BOOL  toBack 
)

Flushes the current accumulated tracker content, if it's the first packet, then when can just return that the packet shall be passed, otherwise to have to refragment the accumulated current packet.
