Subject: [PATCH v3 net-next 02/10] net: dsa: move mib->cnt_ptr reset code to ksz_common.c
Date: Fri, 23 Jul 2021 23:01:00 +0530	[thread overview]
Message-ID: <20210723173108.459770-3-prasanna.vengateshan@microchip.com> (raw)
In-Reply-To: <20210723173108.459770-1-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.
