4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiri Pirko <j...@mellanox.com>
[ 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.
Fixes: b2e345f9a454 ("mlxsw: reg: Add Switch Port VID and Switch Port VLAN
Membership registers definitions")
