Revision 413691384a37fe27f43460226c4160e33140e638 authored by Alexander Lobakin on 08 November 2020, 00:46:15 UTC, committed by Jakub Kicinski on 10 November 2020, 01:15:34 UTC
After updating userspace Ethtool from 5.7 to 5.9, I noticed that NETDEV_FEAT_CHANGE is no more raised when changing netdev features through Ethtool. That's because the old Ethtool ioctl interface always calls netdev_features_change() at the end of user request processing to inform the kernel that our netdevice has some features changed, but the new Netlink interface does not. Instead, it just notifies itself with ETHTOOL_MSG_FEATURES_NTF. Replace this ethtool_notify() call with netdev_features_change(), so the kernel will be aware of any features changes, just like in case with the ioctl interface. This does not omit Ethtool notifications, as Ethtool itself listens to NETDEV_FEAT_CHANGE and drops ETHTOOL_MSG_FEATURES_NTF on it (net/ethtool/netlink.c:ethnl_netdev_event()). From v1 [1]: - dropped extra new line as advised by Jakub; - no functional changes.
