> openvswitch modifies the L4 checksum of a packet when modifying
> the ip address. When an IP packet is fragmented only the first
> fragment contains an L4 header and checksum. Prior to this change
> openvswitch would modify all fragments, modifying application data
> in non-first fragments, causing checksum failures in the
> reassembled packet.

> Changes in v2:
> - Compare frag_off in network byte order rather than host byte order
Applied and queued up for -stable.
