AX_XDP zero-copy support for mlx4

Infrastructure & Networking Software And Drivers Mellanox OFED

Hello, it’s unclear to me at the moment if the mlx4 driver in OFED supports AF_XDP zero-copy All of the documentation I can find only mentions mlx5.

Can you confirm:

  • If mlx4 has support for AF_XDP zero-copy
  • if not, is it planned, or was development of mlx4 drivers halted after OFED 5.1?

Thanks

Dear customer,

If mlx4 has support for AF_XDP zero-copy
No, the mlx4 doesn’t support AF_XDP.

if not, is it planned, or was development of mlx4 drivers halted after OFED 5.1?
The mlx4 is no longer supported. The development of mlx4 drivers was halted for a long time, it’s hard to find out “is it planned” or not.

Thanks!
