qeth.883aa0 <bus ID of the qeth device>: Starting HW checksumming for <network interface name> failed, using SW checksumming
Explanation
The network adapter supports hardware checksumming for IP packages
but the qeth device driver could not start hardware checksumming on the
adapter. The qeth device driver continues to use software checksumming for
IP packages.
User response
None if you do not require hardware checksumming for network traffic. If you want to enable hardware checksumming, 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.
