The bug manifests itself if bit_offset becomes 8 or larger, which happens in some cases if there are multiple fields in the packet-in header that are not a multiple of 8 bits wide. Signed-off-by: Andy Fingerhut <andy_fingerhut@alum.wustl.edu>

I made a small change to one of the existing unit tests, and verified that without the proposed fix the test fails, but with the proposed fix the test passes. |
