This patch initialize stack variables which are used in frag_lowpan_compare_key to zero. In my case there are padding bytes in the structures ieee802154_addr as well in frag_lowpan_compare_key. Otherwise the key variable contains random bytes. The result is that a compare of two keys by memcmp works incorrect.
