const

Verify that packet is correct type

??? check reserved flags zero?

Check packetLength is at least large enough to hold header

Check packet length is multiple of 4

Check actual packet length is large enough.

Make sure there is at least one entry in packet ??? 0 record cvect allowed?

Check packet is at least long enough to hold bytestreamBufferLength array
