[net-next,v3,0/7] dpaa_eth: add XDP support

Message

Camelia Alexandra Groza Nov. 19, 2020, 4:29 p.m. UTC

Enable XDP support for the QorIQ DPAA1 platforms.

Implement all the current actions (DROP, ABORTED, PASS, TX, REDIRECT). No
Tx batching is added at this time.

Additional XDP_PACKET_HEADROOM bytes are reserved in each frame's headroom.

After transmit, a reference to the xdp_frame is saved in the buffer for
clean-up on confirmation in a newly created structure for software
annotations.

Changes in v2:
- warn only once if extracting the timestamp from a received frame fails
  in 2/7

Changes in v3:
- drop received S/G frames when XDP is enabled in 2/7

Camelia Groza (7):
  dpaa_eth: add struct for software backpointers
  dpaa_eth: add basic XDP support
  dpaa_eth: limit the possible MTU range when XDP is enabled
  dpaa_eth: add XDP_TX support
  dpaa_eth: add XDP_REDIRECT support
  dpaa_eth: rename current skb A050385 erratum workaround
  dpaa_eth: implement the A050385 erratum workaround for XDP
