disable-tx-offload command under the
tools command disables tx checksum offload for
eth0 interface of a container referenced by its name.
The need for
disable-tx-offload might arise when you launch a container outside of containerlab or restart a container. Some nodes, like SR Linux, will require correct checksums in TCP packets; thus, it is needed to disable checksum offload on those containers to do checksum calculations instead of offloading it.
containerlab tools disable-tx-offload [local-flags]
With the local mandatory
--container | -c flag, a user specifies which container to remove tx offload.
