Message

Camelia Alexandra Groza Nov. 12, 2020, 6:10 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.


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
