[PATCH v2 3/5] net/hns3: fix loop code variable type mismatch

Dongdong Liu liudongdong3 at huawei.com
Mon May 22 15:17:38 CEST 2023


From: Dengdui Huang <huangdengdui at huawei.com>

Loop conditions are compared with different variable types,
which may cause overflow risks.

Fixes: 67d010346933 ("net/hns3: adjust data type of some variables")
Fixes: 6ee07e3cb589 ("net/hns3: fix insecure way to query MAC statistics")
