Updating members of bridge interface causing DHCP server fail to work

[ccy]

Hi,

I create a bridge with 2 members: OPT1 and OPT2.  I attach a static IPv4 address: 192.168.0.1/24 to the bridge interface.  I also enable the DHCP service for the bridge interface.  Now, hosts connected to opt1 or opt2 can get the IP address lease from the DHCP service.

If I add new member OPT3 to the bridge, I notice the DHCP service stop serving DHCP request although it still active.

I found an error log found in DHCP service: `receive_packet failed on bridge0: Device not configured`

If I restart the DHCP service manually, the DHCP server work as normal.

The middleware has probably destroyed and recreated the bridge interface. I recommend a reboot after network topology changes.

This should be the case.  But restart a router seems a bit over for this case.
