[PR] Derive MAC Address from board unique_id [nuttx-apps]

["Novators (via GitHub)" <gi...@apache.org>]

Novators opened a new pull request, #2332:
URL: https://github.com/apache/nuttx-apps/pull/2332

   ## Summary
   
   Adds an option to derive a MAC Address from the board's unique_id.  Essentially just retrieves the unique_id and performs bit manipulation to ensure it is a valid unicast, locally administered MAC address.  This is useful for Ethernet hardware that does not have a built-in MAC address.  
   
   Requires BOARDCTL_UNIQUEID.
   Adds the NETINIT_UIDMAC Kconfig option.
   
   ## Impact
   
   Allows use of multiple boards on the same network without having to manually configure different MAC addresses for each.
   
   ## Testing
   
   Enable NETINIT_NOMAC and NETINIT_UIDMAC.  Your Ethernet interface should initialize with a unique MAC address based on the board's ID.
   
   Tested on a RP2040 based W5500-EVB-Pico evaluation board and a custom board.
