Update:  The issue is included on the head of the UHD-3.12 branch, but is
not included in the v3.12.0.0 release.  So, be sure to checkout the
v3.12.0.0 tag.

The issue we replicated is the STREAM_CMD_NUM_SAMPS_AND_DONE.  The
continuous streaming issue is still outstanding, but may be related.

Regards,
Michael
