What data strucutre to use for passing 1MB of data to OS for network packet
delivering?
Confused about this question: it's just a buffer, using shared memory to
avoid copy, what else?

I suspect that the interviewer intentionally gives the interviewee a hard
time for this kind of question?

If you know the implementing for net buffer list (either for linux/bsd or
windows), it's an easy question and you can show off your understanding for
network protocol implementing details---- but it seems you don't.
Passing data for network packets is ususally done using a list of buffers (
considering fragmentation). Check NetBufferList on MSDN.

The interviewer said that's not what he is asking.
Of course, it's awkward to pack 1MB of data into one single buffer since
eventually you need to pack packets according to MTU.
That's why I am confused.

NBL is not just for fragmentation and MTU purpose.
anyway, if you don't know what the interviewer is asking, then ask him. DON'
T answer unless you know what the interviewer is aksing. It's OK to take 10
mins to figure out what he is asking (this is very important and indicate if
you can be a good co-worker) than spending 1 mins to "guess" what he is
asking and 9 mins to give an inaccurate answer.
