The qeth device driver could not enable the passthrough mode on the
network adapter. The passthrough mode is required for all network traffic
other than IPv4. In particular, the passthrough mode is required for IPv6
traffic.
User response
None if all you want to support is IPv4 communication. If you want to support
IPv6 or other network traffic apart from IPv4, ungroup and regroup the
subchannel triplet of the device. If this does not resolve the problem,
reboot Linux. If the problem persists, gather Linux debug data and report
the problem to your support organization.
