Re: [PATCH v3 net-next 0/7] udp: Flow dissection for tunnels

From: Tom Herbert <redacted>

v3:
  - Fix build issues with modules that call IPv6 functions and
    CONFIG_INET is not set.
  - Fix compilation error in init'ing .flow_dissect in IPv6 UDP
    offload.

Still doesn't build:

net/ipv6/udp_offload.c:208:19: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
   .flow_dissect = udp6_flow_dissect,
                   ^
net/ipv6/udp_offload.c:208:19: note: (near initialization for ‘udpv6_offload.callbacks.flow_dissect’)
cc1: some warnings being treated as errors

The final argument to udp6_flow_dissect() is marked const but that is not what the
method definition wants.
