Follow-up Comment #8, patch #9751 (project lwip):
> Additionally, since lwiperf only use RAW API, I've assumed it is only
compatible with NO_SYS=1 platforms.
No, RAW API can be used for NO_SYS=0, too.
> Yes, this is a little trick to take care of processing time to send one UDP
frame.
Hmm, if you evenly distribute the time where you call 'udp_send' (or
whatever), why do you need the diff to the wire than? What's the negative
result when leaving this diff out?
> If not evenly distributed, jitter will be very high (according to my
understand of the jitter calculation).
Oh, ok, I hadn't thought about jitter. Maybe it's still a valid solution if
sub-ms timing is not available...
I'll try to merge this by adding defines for the timing.
