	Hello,

	I see, it is the icmp_send() function that uses
inet_select_addr() to select primary source for locally generated
ICMP errors that are sent back to the sender (10.1.1.2).
In your case it is the error_report from the ARP code.

	So, you are correct about the commit but I don't
see any problem with this behavior. IIRC, users preferred
to see primary addresses in the traceroute output.
