The code of skb_drop_reason is a little wild, let's reorganize them.
Three things and three patches:

1) Move the enum 'skb_drop_reason' and related function to the standalone
   header 'dropreason.h', as Jakub Kicinski suggested, as the skb drop
   reasons are getting more and more.

2) use auto-generation to generate the header that convert enum
   skb_drop_reason to string.

3) make the comment of skb drop reasons kernel-doc style.

Menglong Dong (3):
  net: skb: move enum skb_drop_reason to standalone header file
  net: skb: use auto-generation to convert skb drop reason to string
  net: dropreason: reformat the comment fo skb drop reasons
