It sets the receive buffer on a per-application basis.

It sets the same thing, but on a per application basis.

For both, see your OS documentation. FreeRADIUS is just setting a value in the kernel. FreeRADIUS doesn't define what those values do.

No. There is no dependable way to query how much of the buffer is used.
Linux exports /proc/net/udp with some statistics. But to read that, the application has to parse large amounts of text. Other operating systems don't even have that.
Since RAM is *much* cheaper than human salaries, your best bet is to set the recv_buff to a large value, and leave it at that.
