Subject: [PATCH net 2/3] net: hns3: fix VF bandwidth does not take effect in some case
Date: Fri, 14 Feb 2020 09:53:42 +0800	[thread overview]
Message-ID: <1581645223-23038-3-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1581645223-23038-1-git-send-email-tanhuazhong@huawei.com>

From: Yonglong Liu <liuyonglong@huawei.com>

When enabling 4 TC after setting the bandwidth of VF, the bandwidth
of VF will resume to default value, because of the qset resources
changed in this case.

This patch fixes it by using a fixed VF's qset resources according to
HNAE3_MAX_TC macro.

Fixes: ee9e44248f52 ("net: hns3: add support for configuring bandwidth of VF on the host")
