 * non-logging related work in the middle of an event logging transaction.
 * Reparsing packet data allows us to meet these needs while avoiding the need
 * to keep around bookkeeping data on what frames were in a packet, etc.
 *
 * For logging transmitted packets, we actually reuse the same code and reparse
 * the outgoing packet's payload. This again has the advantage that we only log
 * a packet when it is actually queued for transmission (and not if something
 * goes wrong before then) while avoiding the need to keep around bookkeeping
