  Extend the current support of XDP in lan966x with the action XDP_TX and
XDP_REDIRECT.
The first patch introduced a headroom for all the received frames. This
is needed when the XDP_TX and XDP_REDIRECT is added.
The next 2 patches, just introduced some helper functions that can be
reused when is needed to transmit back the frame.
The last 2 patches introduce the XDP actions XDP_TX and XDP_REDIRECT.

v1->v2:
- use skb_reserve of using skb_put and skb_pull
- make sure that data_len doesn't include XDP_PACKET_HEADROOM

Horatiu Vultur (5):
  net: lan966x: Add XDP_PACKET_HEADROOM
  net: lan966x: Introduce helper functions
  net: lan966x: Add len field to lan966x_tx_dcb_buf
