wengzhe opened a new pull request, #7951:
URL: https://github.com/apache/nuttx/pull/7951

   ## Summary
   - patches included:
     - hashtable.h: Added a hashtable implementation 
     - net/nat: Use hashtable to optimize performance 
     - net/nat: Add auto reclaim logic for NAT entries. 
     - doc/nat: update config options 
   
   - Performance tested on simulator:
       ```
       Before optimization:      -25% bandwidth @2k entries, -64% @10k entries
       hashtable size= 32(5bits): -3% bandwidth @2k entries, -14% @10k entries
       hashtable size=256(8bits): -1% bandwidth @2k entries,  -3% @10k entries
       
       Note: Tested on worst performance, the earliest entry will be the worst.
       ```
   
   ## Impact
   - Optimize NAT performance
   
   ## Testing
   - Tested by simulator on Ubuntu 22.04
