Date: Fri, 14 Apr 2017 13:49:34 +0300 From: Nikolay Aleksandrov <nikolay@...ulusnetworks.com> To: netdev@...r.kernel.org Cc: davem@...emloft.net, roopa@...ulusnetworks.com, bridge@...ts.linux-foundation.org, stephen@...workplumber.org, idosch@...lanox.com, Nikolay Aleksandrov <nikolay@...ulusnetworks.com> Subject: [PATCH net-next] net: bridge: notify on hw fdb takeover Recently we added support for SW fdbs to take over HW ones, but that results in changing a user-visible fdb flag thus we need to send a notification, also it's consistent with how HW takes over SW entries.
