Subject: mlxsw: reg: Fix SPVMLR max record count
From: Jiri Pirko <jiri@mellanox.com>
[ 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")
