MCUMGR and net stats over SMP

Hello,

I have the smp server running on our 5340/7002 Wi-Fi device.

I see how the example code uses the stats.h macros to create simple statistics groups.

I have CONFIG_NET_STATISTICS_WIFI and CONFIG_NET_STATISTICS_USER_API set to true and can see interface stats via the shell.

Is there a way to register the Ethernet/WiFi stats so that they will be exposed via the SMP service?

thanks

More info:

I am running on a custom board based on the 7002DK and using SDK 2.3.

The SMP server code is based on the smp sample.

My app has a shell enabled on the USB port.

I am using mcumgr in an OS X zsh terminal.

mcumgr is able to see and retrieve a simple uptime stat I created from the smp server example:

Here are my configuration settings that are relevent to MCUMGR and SMP
