Title:
  [Feature Request] Include support for LACP bonds in initramfs

Status in initramfs-tools package in Ubuntu:
  Triaged

Bug description:
  Feature Request:

  When installing a system over the network using live installer
  (subiquity), you can use the kernel cmdline option ip= [1] to provide
  the network configuration.

  In certain situations, it would be ideal to be able to configure a
  lacp bond during this process. Sometimes the network ports on the
  switch are configured with lacp bond (802.3ad) and the switch won't
  let an interface be brought up unless it sends lacpdus.

  I've discussed this through a subiquity bug [2] and it was mentioned
  that there doesn't seem to be any support in our initramfs for LACP
  bonds [3]. It was requested for a new bug to be filed at the
  initramfs-tools project for such functionality to get included.

  I don't have any use case at the moment, but I've received this
  request in the past when the customer was still using debian
  installer. For debian-installer this was once discussed via a debian
  bug [4] and a patch was proposed [5], but this was never accepted /
  merged.

  Considering that Tte new installer is an _entirely_ different codebase
  than d-i, the lacp support would have to come from the initramfs.
