Subject: [dpdk-dev] [PATCH 09/12] net/hns3: fix PTP caps report
Date: Tue, 13 Apr 2021 19:50:08 +0800 [thread overview]
Message-ID: <1618314611-47978-10-git-send-email-humin29@huawei.com> (raw)
In-Reply-To: <1618314611-47978-1-git-send-email-humin29@huawei.com>
From: Chengwen Feng <fengchengwen@huawei.com>
The PTP depends on special packet type reported by hardware which
enabled rxd advanced layout, so if the hardware doesn't support rxd
advanced layout, driver should ignore the PTP capability.
Fixes: 438752358158 ("net/hns3: get device capability from firmware")
