As discussed in zigpy/zigpy#894 (comment) this is a change in the Gecko SDK v4.3.1.0:

// The NCP no longer supports configuration of packet buffer count at runtime
// using this parameter. Packet buffers must be configured using the
// EMBER_PACKET_BUFFER_COUNT macro when building the NCP project.

https://github.com/SiliconLabs/gecko_sdk/blob/v4.3.1/protocol/zigbee/app/util/ezsp/ezsp-enum.h#L17-L19

The Silicon Labs Multiprotocol uses 255 as the number of buffers, which will automatically assign the maximum number. Since this is a changed behavior for Gecko SDK, we can't fix this on the add-on side.

I think this needs to be addressed in ZHA. I've opened a new issue on the Core side: home-assistant/core#97967.
