Is the receiver buffer size in bytes or samples ?
bytes
Its a direct proxy for SO_REVBUF socket option.

Subject: Re: [Discuss-gnuradio] Setting buffer size when using UHD
The buffer size setting is used across all motherboards in the mimo
setup. So, if specified, its only specified once:
http://www.ettus.com/uhd_docs/manual/html/usrp2.html#resize-the-send-and-receive-buffers
If this is linux, I recommend setting sysctl and letting UHD
automatically pick the size.
sudo sysctl -w net.core.rmem_max=50000000
