Hi Flavio and Ilya,
I have a question about this.
If we do "other_config:userspace-tso-enable=true", it enables both
the TSO and CSUM offload.
Can we enable only the CSUM offload, but not TSO?
So making it a separate configurations?
Because currently, all the "make check-system-userspace" has to add
$ ethtool -K $1 tx off
due to no checksum support.
If we make CSUM offload enabled by default, so we don't need to turn
off tx offload?
Regards,
William
