JIRA: https://issues.redhat.com/browse/RHEL-59091 commit 05c1280 Author: Alexander Lobakin <aleksander.lobakin@intel.com> Date: Thu Aug 29 14:33:38 2024 +0200 netdev_features: convert NETIF_F_NETNS_LOCAL to dev->netns_local "Interface can't change network namespaces" is rather an attribute, not a feature, and it can't be changed via Ethtool. Make it a "cold" private flag instead of a netdev_feature and free one more bit.
