Some DSA tagging protocols change the EtherType field in the MAC header e.g. DSA_TAG_PROTO_(DSA/EDSA/BRCM/MTK/RTL4C_A/SJA1105). On TX these tagged frames are ignored by the checksum offload engine and IP header checker of some stmmac cores.

On RX, the stmmac driver wrongly assumes that checksums have been computed for these tagged packets, and sets CHECKSUM_UNNECESSARY.
