Basically I have a firewall with four nics that uses two of those nics to handle my normal internet connection (firewall/MASQ/NAT) and the other two are assigned to one bridge each. The firewall is also my local caching DNS server and DHCP server, which is also used by the VM:s... But with 4.20 DHCP replies disappeared before entering the bridge - i couldn't even see them in tcpdump! (all nics are ixgbe on a atom soc) I'm currently running a kernel with that patch reversed but I'm also wondering about possible ways forward since I'm reverting a fix from someone else...
