4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jiri Pirko <[email protected]> [ Upstream commit f004ec065b4879d6bc9ba0211af2169b3ce3097f ] The num_rec field is 8 bit, so the maximal count number is 255. This fixes vlans not being enabled for wider ranges than 255.
