Subject: [PATCH net-next 03/12] vxlan_core: move some fdb helpers to non-static
Date: Sun, 20 Feb 2022 14:03:56 +0000 [thread overview]
Message-ID: <20220220140405.1646839-4-roopa@nvidia.com> (raw)
In-Reply-To: <20220220140405.1646839-1-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.
