From cca28ceac7c7857bc2d313777017585aef00bcc4 Mon Sep 17 00:00:00 2001 From: Muhammad Husaini Zulkifli Date: Wed, 17 May 2023 08:18:12 +0800 Subject: igc: Remove delay during TX ring configuration 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.
