net: TestInterfaceArrivalAndDepartureZoneCache is broken on linux-arm64 #61414
Description
I recently rebuilt our linux-arm64 image to include the iproute2 package, which caused the skip at https://cs.opensource.google/go/go/+/master:src/net/interface_unix_test.go;l=193;drc=f229e7031a6efb2f23241b5da000c3b3203081d6 to stop happening. Unfortunately the test is failing:
--- FAIL: TestInterfaceArrivalAndDepartureZoneCache (0.00s)
