@akos011221 @ti-mo There was conflicts backporting #44513, namely #43479 refactored a lot of this code. I went ahead and tried to just do the backport myself. Please take a look to ensure the changes are correct/equivalent.

Failing consistently at creating NodeGroup in ci-eks.
I already saw this and I believe it simply needs a rebase, going to do it right now.

[ upstream commit 61e04f7 ]
[ backporters notes: overlay.go did not previously prior to 43479.
        This moves this logic to where the bpf overlay was previouly
        created at replaceOverlayDatapath ]

The InterfaceMAC field is not filled from the tunnel dev's MAC address.
Because of this the BPF program for the overlay resolves to
00:00:00:00:00:00, sending this broken response to the VTEP ARP lookup
request.

Fixes: #44453
