[Patch net-next 06/11] net: dsa: microchip: move the port mirror to ksz_common

From: Arun Ramadoss
Date: Fri Jun 17 2022 - 04:45:02 EST


This patch updates the common port mirror add/del dsa_switch_ops in
ksz_common.c. The individual switches implementation is executed based
on the ksz_dev_ops function pointers.
