Pulled, but long term you should shore up your datastructures to
handle that issue in patch #3.

Make a common header:

	struct tt_entry_common {
		u8 addr[ETH_ALEN];
		struct hlist_node hash_entry;
	};

Then use that at the beginning of both structures:

	struct tt_local_entry {
		struct tt_entry_common common;
		unsigned long last_seen;
		...
	};

	struct tt_global_entry {
		struct tt_entry_comomn common;
		struct orig_node *orig_node;
		...
	};

And &p->common is what gets passed into tt_response_fill_table().
