Description of problem:
The kernel panic occurs if a bridge device is connected with physical NIC and UDP packets are transmitted via the bridge device.

The kernel panic occurs when all the following conditions consist:
- The kernel version is RHEL6(2.6.32-71.xx.el6).
- The NETIF_F_HW_CSUM of the physical device connected with the bridge device is available.
- The udp-fragmentation-offload function of the bridge device is available(ON).
- The udp-fragmentation-offload function of the physical NIC is unavailable(OFF).
- IPv6 protocol
- The size of the UDP datagram exceeds MTU. (fragmentation is necessary)

The system configuration:
Test_program ---> UDP/IP ---> bridge(br0) ---> NIC(eth0) ---> network

Version-Release number of selected component (if applicable):
kernel-2.6.32-71.el6 

How reproducible:
Always with the reproducer

Steps to Reproduce:
1. gcc -o udp6_send udp6_send.c 
2. run reproducer.sh (put udp6_send in the same directory).
  
Actual results:
Kernel Panic occurs.

Expected results:
Kernel Panic doesn't occur.
