From 89982e050110813244301f9def2d5652c2b9568e Mon Sep 17 00:00:00 2001 From: Jie Wang Date: Fri, 12 May 2023 18:00:13 +0800 Subject: [PATCH] net: hns3: fix reset delay time to avoid configuration timeout [ Upstream commit 814d0c786068e858d889ada3153bff82f64223ad ] Currently the hns3 vf function reset delays 5000ms before vf rebuild process. In product applications, this delay is too long for application configurations and causes configuration timeout. According to the tests, 500ms delay is enough for reset process except PF FLR. So this patch modifies delay to 500ms in these scenarios.
