Thank you for confirming jumbo frame support.
I am unable to achieve MTU 9000 on my RPi Pro — packets fail above 2032 bytes in ping tests."
I'm assuming the CM4 module uses the Broadcom BCM2711 Ethernet controller and this has a hard physical limit on its internal buffer, which in the real world restricts it to MTU 2032
In most optimized Linux kernels (including Audiolinux), the maximum "Mini-Jumbo" frame size for a Raspberry Pi 4 architecture is exactly 2032 or 2048 bytes. Attempting to force 9000 will simply result in dropped packets or a total loss of connection.
Am I missing something here?
