From 68b654e9eb5b18776224f976ebd5a486d55a4014 Mon Sep 17 00:00:00 2001 From: Muhammad Husaini Zulkifli Date: Wed, 17 May 2023 08:18:12 +0800 Subject: [PATCH] igc: Remove delay during TX ring configuration [ Upstream commit cca28ceac7c7857bc2d313777017585aef00bcc4 ] Remove unnecessary delay during the TX ring configuration. This will cause delay, especially during link down and link up activity. Furthermore, old SKUs like as I225 will call the reset_adapter to reset the controller during TSN mode Gate Control List (GCL) setting. This will add more time to the configuration of the real-time use case. It doesn't mentioned about this delay in the Software User Manual. It might have been ported from legacy code I210 in the past.
