See commit msg.

TODOs till final release:

  • edt map removal if feature not used
  • adapt edt drop horizon for any proto to 2s in general (incl UDP)
  • finalize l7 support
  • Implement for NodePort backend Pods (double check if supported)

bpf: fix skb pacing for traffic from pods
1552a10 
On top of [0] patches.

Consider a socket which has SO_MAX_PACING_RATE of 4Gbit/s & the socket being
part of a Pod. This is currently broken given skb->tstamps are cleared on
redirect even though fq in hostns manages the socket's pacing. This fixes
BBR and SO_MAX_PACING_RATE for Pods.

Before (rates un{stable,predictable}):

We are working on a kernel side solution to retain skb->tstamps which
would fix this issue and result in a stable 4Gbit/s rate for this
example. Once that is merged we can reenable BBR from BWM side for
those kernels (and fallback to cubic for those that do not have it).

bwm: temporarily disable setting bbr until we have a pacing fix
1dcc229 
[ upstream commit c233140 ]

Consider a socket which has SO_MAX_PACING_RATE of 4Gbit/s and the
socket being part of a Pod. This is currently broken given skb->tstamps
are cleared on BPF redirect as well as netns traversal even though
fq in hostns manages the socket's pacing. Rates would result being
unpredictable:

We are working on a kernel side solution to retain skb->tstamps which
would fix this issue and result in a stable 4Gbit/s rate for this
example. Once that is merged we can reenable BBR from BWM side for
those kernels (and fallback to cubic for those that do not have it).
