From 4f8afb680f1343a2ce42d5ff3c31e8486650a3a6 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Sun, 8 May 2022 11:08:16 +0300 Subject: [PATCH] mlxsw: spectrum: Move handling of VRF events to router code Events involving VRF, as L3 concern, are handled in the router code, by the helper mlxsw_sp_netdevice_vrf_event(). The handler is currently invoked from the centralized dispatcher in spectrum.c. Instead, move the call to the newly-introduced router-specific notifier handler.
