Subject: [PATCH v2 1/7] net/hns3: fix order of clearing imissed register in PF
Date: Thu, 5 May 2022 20:27:01 +0800
Message-ID: <20220505122707.61182-2-humin29@huawei.com> (raw)
In-Reply-To: <20220505122707.61182-1-humin29@huawei.com>

From: Huisong Li <lihuisong@huawei.com>

Clearing imissed registers in PF hardware depends on the 'drop_stats_mode'
in struct hns3_hw. The variable is initialized after the
"hns3_get_configuration". But, in current code, the clearing operation runs
before the function. So this patch fixes this order. In addition, this
patch extracts a public function to initialize and uninitialize statistics
to improve the maintainability of these codes.

Fixes: 3e9f3042d7c8 ("net/hns3: add imissed packet stats")
