Hi,I am unable to send and receive packets directly on the lan1 interface when it is not part of a bridge.
I have seen this on today's OpenWrt master.
I changed the OpenWrt network configuration like this:
--------------------------
root@OpenWrt:/# cat /etc/config/network
config interface 'loopback'
option device 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fd39:7fe0:0309::/48'
config device
option name 'lan1'
option macaddr '9a:0d:67:06:9a:40'
config interface 'lan'
option device 'lan1'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'
root@OpenWrt:/#
--------------------------
The interface is configured and brought up correctly:
--------------------------
root@OpenWrt:/# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN

I see that some packets are received, but the RX counter do not increase
anymore:

--------------------------
In wireshark on a connected host I do not see any packets from this
device, but the link is up.
When I use OpenWrt's default network configuration using a bridge, network works like expected. I took care of the VLAN 100 which is used by default, but this setup does not use any VLAN.
I would like to use a very similar configuration for the failsafe mode which is also not working correctly.
