Subject[Patch net-next v12 03/13] net: dsa: move mib->cnt_ptr reset code to ksz_common.c
Date
From: Prasanna Vengateshan <prasanna.vengateshan@microchip.com>

mib->cnt_ptr resetting is handled in multiple places as part of
port_init_cnt(). Hence moved mib->cnt_ptr code to ksz common layer
and removed from individual product files.
