I am scratching my head, but I thought you told me that ethtool -K eth0 tso off ethtool -K eth0 tx on was working ? And, given that when you perform "ethtool -K eth0 tx off", TSO is automatically off... tx checksums work, TSO doesnt work, therefore TSO is broken ? -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
