Documentation
Each flow entry includes a match, which essentially defines packet-matching condition. Fields that are left Nothing are wildcards.
Constructors
isExactMatch :: Match -> BoolSource
Return True if given Match represents an exact match, i.e. no
wildcards and the IP addresses' prefixes cover all bits.
getExactMatch :: PortID -> GetE MatchSource
Utility function to get an exact match corresponding to a packet (as given by a byte sequence).
frameToExactMatch :: PortID -> EthernetFrame -> MatchSource
