when containerlab starts linux container, their lo and eth0 interfaces are configured with tx checksum offload
that makes it impossible to talk to SRL nodes since SRL validates the checksums of incoming packets.

Investigate if its possible to programmatically change into container namespace and configure tx off for lo and eth0 interfaces without requiring ethtool to be available in container
