qeth.c98a58 <bus ID of the qeth device>: Enabling HW TX checksumming for <network interface name> failed, using SW TX checksumming

Explanation

The network adapter supports hardware checksumming for outgoing IP packages but the qeth device driver could not enable hardware TX checksumming on the adapter. The qeth device driver continues to use software checksumming for outgoing IP packages.

User response

None if you do not require hardware checksumming for outgoing 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.
