From 77d964e66cfad007db14077fc952ce13bdaa2733 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Wed, 2 Aug 2017 09:56:05 +0200 Subject: [PATCH] mlxsw: spectrum_router: Refresh offload indication upon group refresh Now that we provide offload indication using the nexthop's flags we must refresh the offload indication whenever the offload state within the group changes. This didn't matter until now, as offload indication was provided using the FIB info flags and multipath routes were marked as offloaded as long as one of the nexthops was offloaded.
