Change #253808

Comments

netmap: set the captured length appropriately.
If there's no capture filter, set it to the minimum of the length
provided by netmap and the length specified when the device was opened.

If there is a capture filter, set it to the minimum of the length
provided by netmap and the length returned by the capture filter
program.

That way, "tcpdump -s", etc. will give you shorter packets, so you don't
have to write all the data out or parse it.
