Subject[PATCH 5.6 069/167] net: dsa: b53: b53_arl_rw_op() needs to select IVL or SVL
Date
From: Florian Fainelli <f.fainelli@gmail.com>

[ Upstream commit 64fec9493f7dc9bdd7233bcfe98985c45bd0e3c1 ]

Flip the IVL_SVL_SELECT bit correctly based on the VLAN enable status,
the default is to perform Shared VLAN learning instead of Individual
learning.
