[PATCH net v2 5/5] net: dsa: b53: b53_arl_rw_op() needs to select IVL or SVL
From: Florian Fainelli
Date: Mon Apr 20 2020 - 23:28:06 EST
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.
Fixes: 1da6df85c6fb ("net: dsa: b53: Implement ARL add/del/dump operations")
