Hi All,
I've been looking at the eventdev API from a use-case point of view, and I'm unclear on a how the API caters for two uses. I have simplified these as much as possible, think of them as a theoretical unit-test for the API :)
Fragmentation:
1. Dequeue 8 packets
2. Process 2 packets
3. Processing 3rd, this packet needs fragmentation into two packets
4. Process remaining 5 packets as normal
What function calls does the application make to achieve this?
In particular, I'm referring to how can the scheduler know that the 3rd packet is the one being fragmented, and how to keep packet order valid.
Dropping packets:
1. Dequeue 8 packets
2. Process 2 packets
3. Processing 3rd, this packet needs to be dropped
4. Process remaining 5 packets as normal
What function calls does the application make to achieve this?
Again, in particular how does the scheduler know that the 3rd packet is being dropped.
Regards, -Harry
