284 | Basically, heres what this should do: | |
285 | 1) Determine correct packet handler for this packet | |
286 | 2) Mark the packet handled (so it can be dequeued in purge_queue()) | |
287 | 3) Send the packet to the packet handler | |
288 | 4) Go to next packet in the queue and start over | |
289 | 5) When done, run purge_queue() to purge handled commands | |
290 | ||
291 | Note that any unhandlable packets should probably be left in the | |
292 | queue. This is the best way to prevent data loss. This means | |
293 | that a single packet may get looked at by this function multiple | |
294 | times. This is more good than bad! This behavior may change. | |
