[GSoC 2021] Beagle BSP USB OTG Support

[Ahamed Husni]

Hi,

I tried the CDC Ethernet in FreeBSD. My Laptop detects an ethernet
<https://dms.uom.lk/s/QrzEsZAiSnWnQdk> interface with an IPv6.
I tried to ping the IPv6, but it didn't work
<https://dms.uom.lk/s/in6R2foWYwFWcdX>. The serial and ethernet works. I'll
check the mass
storage.
