These operations imply that 7.7.7.5 is configured on some interface on
the host. Most likely the VF representor itself, as that aids with ARP
resolution. Is that so?

The tunnel endpoint IP address is configured on VF that is represented
by enp8s0f0_0 representor in example rules. The VF is on host.

This is very confusing, are you saying that the 7.7.7.5 is configured
both on VF and VFrep? Could you provide a full picture of the config
with IP addresses and routing?

No, tunnel IP is configured on VF. That particular VF is in host [..]

What's the motivation for that? isn't that introducing 3x slow down?
