Subject: [PATCH net-next v3 04/12] vxlan_core: move some fdb helpers to non-static
Date: Tue, 1 Mar 2022 05:04:31 +0000 [thread overview]
Message-ID: <20220301050439.31785-5-roopa@nvidia.com> (raw)
In-Reply-To: <20220301050439.31785-1-roopa@nvidia.com>
This patch moves some fdb helpers to non-static
for use in later patches. Ideally, all fdb code
could move into its own file vxlan_fdb.c.
This can be done as a subsequent patch and is out
of scope of this series.
