Subject: [dpdk-dev] [PATCH 3/4] net/hns3: support multiple TC MAC pause
Date: Sun, 13 Jun 2021 11:05:07 +0800 [thread overview]
Message-ID: <1623553508-5478-4-git-send-email-humin29@huawei.com> (raw)
In-Reply-To: <1623553508-5478-1-git-send-email-humin29@huawei.com>
From: Huisong Li <lihuisong@huawei.com>
MAC PAUSE can take effect on a single TC or multiple TCs, depending on the
hardware. For example, the Kunpeng 920 supports MAC pause in a single TC,
and the Kunpeng 930 supports MAC pause in multiple TCs. This patch
supports MAC PAUSE in multiple TC for some hardware.
