From: Petr Machata Date: Fri, 7 Dec 2018 19:55:12 +0000 (+0000) Subject: mlxsw: spectrum_nve: Add mlxsw_sp_nve_ops.fdb_replay X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a6ef5a48a32fe87af947e22973a409870bc63d0d;p=linux.git mlxsw: spectrum_nve: Add mlxsw_sp_nve_ops.fdb_replay A replay of FDB needs to be performed so that the FDB entries existing at the NVE device are offloaded. How the replay is done depends on NVE device type, and therefore add a per-NVE-type operation. Implement the operation for the sole NVE device type currently supported by mlxsw, VXLAN.
