[PATCH] s390: TSO related fixes in qeth driver
Jeff, I'm sorry seems that they have not been sent out either ... ok here they come ... [patch 3/4] s390: TSO related fixes in qeth driver From: Frank Pavlic <pavlic@de.ibm.com> TSO related fixes : - changing value of large_send attribute while network traffic is running caused program check and thus device recovery. - Due to hardware restriction discard packet when it exceeds 60K otherwise qeth will cause program checks and thus traffic stall when trying to send such huge packets.
