From d54151aa0f4b5c89561705a00d8a5ebb4230028c Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Tue, 11 Apr 2023 21:01:49 +0300 Subject: net: ethtool: create and export ethtool_dev_mm_supported() Create a wrapper over __ethtool_dev_mm_supported() which also calls ethnl_ops_begin() and ethnl_ops_complete(). It can be used by other code layers, such as tc, to make sure that preemptible TCs are supported (this is true if an underlying MAC Merge layer exists).
