qeth.96f275 <bus ID of the qeth device>: Starting
proxy ARP support for <network interface name> failed
Explanation
The qeth device driver could not start proxy ARP
support on the network adapter.
User response
None if you do not require proxy ARP support. If
you need proxy ARP, 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.
