net: dsa: hellcreek: Calculate checksums in tagger
In case the checksum calculation is offloaded to the DSA master network
interface, it will include the switch trailing tag. As soon as the switch strips
that tag on egress, the calculated checksum is wrong.
Therefore, add the checksum calculation to the tagger (if required) before
adding the switch tag. This way, the hellcreek code works with all DSA master
interfaces regardless of their declared feature set.
