Subject: [9fans] Pi3 with 2 nics
Topicbox-Message-UUID: b9f01c52-ead9-11e9-9d60-3106f5b1d025

Hi all,
I have a pi3 with normal and wifi eth interfaces under the same stack.
Wifi address is 10.12.12.15/16, the address of the other nic is
10.11.12.15/16,
/net seems to be correct, the connection to the AP is up and running.
But:

(1) ping wifi 10.12.12.15 doesn't work when the Rj45 is unplugged
(2) ping wifi 10.12.12.15 works when the Rj45 is plugged
(3) the arp tables on the net all have a correct 10.12.12.15 entry
(4) ip/ping -a to 10.11.x.x or 10.12.x.x always displays
      10.11.12.15 -> ...   and doesn't work when the cable is unplugged.
(5) with/without cable, "snoopy /net/ether1" (wifi nic) shows
      icmp packets when pinging.

I'm quite confused.
Could anyone kindly tell me where is my mistake  ?

Thank you so much
adriano
