Revision 565ce8f32ac4a233b474f401e1d3e7e1de0a31fd authored by Nikolay Aleksandrov on 27 June 2016, 16:34:42 UTC, committed by David S. Miller on 29 June 2016, 09:33:35 UTC
I made a dumb off-by-one mistake when I added the vlan stats counter dumping code. The increment should happen before the check, not after otherwise we miss one entry when we continue dumping.
