From 37956d78b8f0c5560421f83d1a5e337ee81c685c Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Thu, 20 Oct 2016 16:05:43 +0200 Subject: [PATCH] mlxsw: spectrum_router: Make mlxsw_sp_router_fib4_del return void and remove warn The function return value is not checked anywhere. Also, the warning causes huge slowdown when removing large number of FIB entries which were not offloaded, because of ordering issue. Ido's preparing a patchset to fix the ordering issue, but that is definitelly not net tree material.
