Tcpdump does not always work correctly with QETH driver in layer 3 mode
This document (3396742) is provided subject to the disclaimer at the end of this document.
Tcpdump, and related tools using libpcap, do not always work correctly if tracing on qeth devices in layer 3 mode.
The latter can be done "on the fly" with the following command from a shell:
echo 1 > /sys/bus/ccwgroup/drivers/qeth/CCW/fake_ll
(replace CCW with the CCW of the device, for example: 0.0.fe30)
For more information please refer to the Device Driver manual (SC33-8289-03) at http://www-128.ibm.com/developerworks/linux/linux390/october2005_documentation.html
