Please add a programmatical interface to do the lookups you need
rather than exporting this symbol externally.

As best I can tell you're trying to "find gro receive by type"
and "find gro complete by type".  So function signatures ought
to look something like.

struct packet_offload *gro_find_receive_by_type(__be16 type);
struct packet_offload *gro_find_complete_by_type(__be16 type);

Thanks.
