Change 167405 by anchie@anchie_desnimis on 2009/08/16 13:58:46

	All mbufs containing ND messages are tagged in nd6_*_output()
	functions with PACKET_TAG_ND_OUTGOING. On one place nd6_na_input()
	calls directly nd6_output_lle(), so the packet does not traverse
	through nd6_*_output() and ends up being untagged.
