| Subject: net: hns3: fix VF bandwidth does not take effect in some case |
| |
| From: Yonglong Liu <liuyonglong@huawei.com> |
| |
| [ Upstream commit 19eb1123b4e9337fe20b1763fec528f837ec6568 ] |
| |
| 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") |
