Hi, What's the correct way to disble TSO (TCP Segmentation Offload) in RHEL5? I have tried adding those options in ifcfg-ethX configuration file: # grep ETHTOOL /etc/sysconfig/network-scripts/ifcfg-eth0 ETHTOOL_OPTS="tso off" And also with: ETHTOOL_OPTS="-K eth0 tso off" But when restating the server TSO is enabled: # ethtool -k eth0 tcp segmentation offload: on As a temporary solution, I'm executing this command in a start script: /sbin/ethtool -K eth0 tso off But I think it can be configured in network configuration files, any idea to solve this? thanks!!
