Subject: [PATCH net-next 1/5] net: bridge: add dynamic flag to switchdev notifier
Date:   Mon, 30 Jan 2023 18:34:25 +0100
Message-Id: <20230130173429.3577450-2-netdev@kapio-technology.com>
In-Reply-To: <20230130173429.3577450-1-netdev@kapio-technology.com>
References: <20230130173429.3577450-1-netdev@kapio-technology.com>
MIME-Version: 1.0
Organization: Westermo Network Technologies AB
Content-Transfer-Encoding: 8bit
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.
