s390/qeth: display warning for OSA3 RX/TX checksum offloading
When RX/TX checksum offloading is turned on and the adapter is
an OSA 3 card in layer 3 mode, the checksum offloading is only
performed when both peers use different adapters. If both peers
share an OSA 3 card, communication is a memory copy and
checksum offloading is not performed.
This patch adds a warning to inform the administrator.
OSA 3 in layer 2 mode does not offer the RX/TX checksum
offload feature.
