From 1828e308421c8a535e89c6acaa5d18b42308fb1e Mon Sep 17 00:00:00 2001 From: Jie Wang Date: Mon, 3 Apr 2023 14:11:07 +0800 Subject: [PATCH] net: hns3: modify reset delay time to avoid configuration timeout driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6SLBO CVE: NA ---------------------------------------------------------------------- Currently the vf function reset needs to delay 5000ms for stack recovery. This is too long for product configurations and cause configuration failures. According to the tests, 500ms delay is enough for reset process except PF FLR. So this patch adapts this delay in these scenarios.
