   > Can you expand on why this change is necessary? In particular, I'd like to understand what the difference between free and destroy is. It'd be good to document these differences more thoroughly in the code too.
   
   Hi , @antmerlino 
   
   Thanks for review, 
   In the process of TCP / IP stack optimization, I have a requirement to delete an entry from the iob queue list, but the current implementation of IOB does not have this support, look at the API implementation further, I find that the free semantics seems to be more suitable for deleting an entry, and the current free processing is to destroy the entire iob queue. I think it seems that destroy is more suitable for this operations
