Subject: mlxsw: reg: Fix SPVMLR max record count

From: Jiri Pirko <[email protected]>

[ Upstream commit e9093b1183bbac462d2caef3eac165778c0b1bf1 ]

The num_rec field is 8 bit, so the maximal count number is 255. This fixes vlans learning not being enabled for wider ranges than 255.

Fixes a4feea74cd7a ("mlxsw: reg: Add Switch Port VLAN MAC Learning register definition")
