I am running DESIGNATED DRIVER(Bleeding Edge, r48016) on WR941ND_v5 and having this problem:

My eth1 is bound to lan ports, as specified in the /etc/config/network:
config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fda3:7e09:64d1::/48'
config interface 'lan'
option type 'bridge'
option ifname 'eth1'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'
config interface 'wan'
option ifname 'eth0'
option proto 'dhcp'
config interface 'wan6'
option ifname 'eth0'
option proto 'dhcpv6'
config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'
config switch_vlan
option device 'switch0'
option vlan '1'
option ports '0 1 2 3 4'
After some trials I have found that the eth1 goes down and up when a lan-port link gets up(active), that is, when one of local hosts under the router boots up or resumes from sleep. Not always but it's the only case for me.
I don't know it's a normal behavior or not. But, I am worried if it might affect the connections of the other hosts under the router.
Thanks.
PS
The logread at the moment of booting a local host is like:
