Subject: [PATCH net-next v4 0/4] mtk_eth_soc rx vlan offload improvement + dsa hardware untag support

This series improves rx vlan offloading on mtk_eth_soc and extends it to
support hardware DSA untagging where possible.
This improves performance by avoiding calls into the DSA tag driver receive
function, including mangling of skb->data.

This is split out of a previous series, which added other fixes and
multiqueue support

Changes in v4:
 - fix reverse christmas tree in dsa patch
 - use skb_dst_drop to support metadata dst refcounting
 - disable dsa untag offload in mtk_eth_soc if xdp is used

Felix Fietkau (4):
  net: dsa: add support for DSA rx offloading via metadata dst
  net: ethernet: mtk_eth_soc: pass correct VLAN protocol ID to the
    network stack
  net: ethernet: mtk_eth_soc: add support for configuring vlan rx
    offload
  net: ethernet: mtk_eth_soc: enable hardware DSA untagging
