Hi All,
We are seeing *ASSERT (vec_len (hw_if0->hw_address) == 6);* being hit in
*arp_mk_reply*() . This is happening on *19.08. *
We are having worker threads and a main thread.
As such , the hw_if0 appears to be valid(the pointer and content).
*But the length of the vector is 15. *
I have attached some information from the core file.
