Subject: [PATCH v2 01/11] net/hns3: fix uninitialized RTC time
Date: Fri, 2 Jun 2023 19:41:55 +0800	[thread overview]
Message-ID: <20230602114205.29589-2-liudongdong3@huawei.com> (raw)
In-Reply-To: <20230602114205.29589-1-liudongdong3@huawei.com>

From: Huisong Li <lihuisong@huawei.com>

Driver doesn't initialize RTC time during probe phase, which
lead to an inaccurate time.

Fixes: 38b539d96eb6 ("net/hns3: support IEEE 1588 PTP")
Cc: stable@dpdk.org
