Hi Gleb,

when I was looking at the code, I was also wondering if it would make
more sense to check for M_LOOP.

However, isn't the rcvif wrong for the first two received packets? I
would expect it always to be the loopback interface. Is that expectation
wrong?

I also have an additional question:
Why is this check protected by an (ia != NULL) condition? It does not make
any use of ia?

Best regards
Michael
