I did not add any new sysfs knobs for TSO. The old one was just moved
from the core part of the driver to the L3 discipline. I know ethtool
is the way to configure TSO and I would be happy to drop sysfs off, but
we have to keep this legacy interface because of our customers and
distributors. If you say there is no way to keep it let me know and I
will rework the patch.
