From a257f188b72bf0f8b5a08efba174373f5708ff0c Mon Sep 17 00:00:00 2001 From: Usha Ketineni Date: Thu, 8 Aug 2019 07:39:24 -0700 Subject: ice: Limit Max TCs on devices with more than 4 ports This patch limits the max TCs set by the driver to the value provided by the firmware as per the capabilities of the device. Otherwise, hard coding to 8 TC max would fail the device configurations with more than 4 ports.
