Details

Description:
After upgrading to kernel 4.3.3-1 (or 4.3.3-2) iptables TEE is resulting to kernel panic

Additional info:
* kernel version(s) : 4.3.3-1 & 4.3.3-2
* working on version : 4.2.5-1

Steps to reproduce:
I have one openvpn (tun) interface (tnic_vpn) I want to copy the traffic from, I am using :
iptables -t mangle -A PREROUTING -i tnic_vpn -j TEE --gateway 10.20.55.1
iptables -t mangle -A POSTROUTING -o tnic_vpn -j TEE --gateway 10.20.55.1

As soon a a packet is sent -> kernel panic.

This was working perfectly on kernel 4.2.5-1 for multiple weeks without any issue.
This task depends upon
