Missing NFSv4 support?

[vitosx]

I can't mount NFS shares using protocol version 4 in any way... and after a check using rpcinfo it looks like my NAS does not support it.

I did not even consider it not might be there when I decided to buy AS3202T. It might not have some bells and whistles the competition has, but being a NAS device it should do at least one thing good - support up to date file sharing protocols!

Maybe there is a way to activate it and it is just missing from the interface? Synology and QNAP both have separate checkboxes for enabling NFSv4.
