Sorry, I meant to say mcast-snooping path, not patch.
-Thanks

 Subject: openvswitch-2.5.0, mcast-snooping patch isn't validating IP checksum
   
Using openvswitch-2.5.0, user-space mode with Linux 2.6 based kernels.IGMP 
packets from NIC driver are handed over to Linux stack using netif_rx(). 
openvswitch is picking packets from net_device using netlink.
As this path bypasses Linux kernel's IP stack, Linux kernel isn't validating IP 
checksum.
Looks like, when packet enters vswitchd, it doesn't seem to validate IP header 
checksum for the IGMP packets and 
is directly delivering them to mcast-snoop module.
Is this a deliberate one to skip validating IP header checksum for IGMP packets 
in this scenario or I am missing something here.
-Thanks
