Length fields are not being checked

[erickvermot]

length fields are not beeing checked. (pg 50) - "OpenFlow is a simple binary protocol, therefore invalid OpenFlow messages generated by OpenFlow implementations will in general result in the message having the wrong length or some fields having invalid values (see 7.1.3). It is recommended to monitor those conditions to detect non-compliant implementations."

• when length is passed as a parameter, as in flow_match, maybe length should be computed locally, or checked for validity before message is sent.
