XDP option missing on version 1.3


The documentation mentions that XDP is supported on version 1.3, however, I cannot see it after downgrading to 1.3.

set interfaces ethernet eth0 xdp

  Configuration path: interfaces ethernet eth0 [xdp] is not valid
  Set failed


It was removed in Login
as experimental feature

This is an extension to commit 801c5235 ("xdp: T2666: disable this highly
experimental feature in 1.3 LTS") by dropping all XDP references in the
equuleus codebase.
