Subject: [patch net 1/2] mlxsw: reg: Fix SPVM max record count

From: Jiri Pirko <jiri@...lanox.com>

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")
