Do late packets always get dropped by the USRP? What happens if its buffers

The stream args have a policy parameter. Also, these args can be set

Ok, makes sense. So lets say I scheduled 20 minutes of bursts (1 second
period with 50/50 duty cycle) and I started the flowgraph 10 minutes
late. With the next_burst policy, could I rely on the USRP to
dutifully drop all late bursts? Are the packets dropped in the Ethernet
buffer or does
Run volk/lib/test_all from the build dir
If a kernel fails, it will tell you which one, start commenting out its
implementations in the source dir volk/kernels/volk/volk_*.h until the
test works. We narrow down suspect implementation and fix.

Does that directory exist for you? Did you follow the build
