Vladimir, so the DSA switch will not copy the offload flags when a tag requests tail room? At least it will work. Now, if the offload HW does support that tag, what would be the options? Set the slave port checksum flag from userland? It would be nice to have some type of "magic trick" to have it enabled by default. I'm already expecting a no, but wouldn't it be a nice case for a DSA property in the device tree? Regards, Luiz
