Subject: [RFC PATCH net-next 1/5] net: bridge: add dynamic flag to switchdev notifier
Date:   Tue, 17 Jan 2023 19:57:10 +0100
Message-Id: <20230117185714.3058453-2-netdev@kapio-technology.com>
In-Reply-To: <20230117185714.3058453-1-netdev@kapio-technology.com>

Precedence: bulk

To be able to add dynamic FDB entries to drivers from userspace, the
dynamic flag must be added when sending RTM_NEWNEIGH events down.
