net-next, please read the whole doc Eric linked

Personally IDK if this is sufficiently semantically significant
to warrant merging. FRAG_FAILED means "unidentified error during
fragmentation"? ip_frag_next() only returns -ENOMEM and
SKB_DROP_REASON_NOMEM already exists, so just use that.

FRAG_OUTPUT_FAILED means something failed in output so it'd be more
meaningful to figure out what failed there, instead of adding 
a bunch of ${CALLER}_OUTPUT_FAILED
