CI failure

The Cilium E2E upgrade workflow on the v1.15 branch appears to have a success rate at around 35% [1] since having been enabled again ~3 weeks ago [2]. From a quick look, most of the failures appear to be due to no-unexpected-packet-drops:

❌ Found unexpected packet drops:
{
  "labels": {
    "direction": "EGRESS",
    "reason": "Missed tail call"
  },
  "name": "cilium_drop_count_total",
  "value": 1
}
