[lwip-devel] [task #6827] etharp could need some tuning

[Simon Goldschmidt]

Follow-up Comment #38, task #6827 (project lwip):

OK, checked it in.

One question: etharp currently uses code like this to copy ethernet
addresses:

k = 6;
while(k > 0) {
 k--;
 ...;
}

Is that faster than

for (k = 0; k < 6; k++) {
 ...;
}

or why is it that way? I didn't change it since the difference was not
measurable on my embedded target...
