QNEthernet using 80k RAM

Just a quick update. I have tested with the last version which integrates the "buffers-in-RAM2" modification and everything seems to be working great. Gained extra 15K bytes of RAM1 space, which is precious for my application. Many thanks!
 
The latest QNEthernet push further reduces RAM1 usage by about 27KiB with the current configuration by moving lwIP's memory pools to RAM2, along with some other hundreds-of-bytes changes.

no before - here is after/current with TD 1.58b3:
Code:
"C:...\arduino_build_[B]IPerfServer.ino[/B]/..."
teensy_size: Memory Usage on Teensy 4.1:
teensy_size:   FLASH: code:144608, data:20376, headers:9092   free for files:7952388
teensy_size:    RAM1: variables:30112, code:141572, padding:22268   free for local variables:330336
teensy_size:    RAM2: variables:79392  free for malloc/new:444896

And it runs
