From 87b0984ebfabafcfe959e52ca5cdab5eeb2d60c0 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Wed, 16 Jan 2019 23:06:50 +0000 Subject: net: Add extack argument to ndo_fdb_add() Drivers may not be able to support certain FDB entries, and an error code is insufficient to give clear hints as to the reasons of rejection. In order to make it possible to communicate the rejection reason, extend ndo_fdb_add() with an extack argument. Adapt the existing implementations of ndo_fdb_add() to take the parameter (and ignore it). Pass the extack parameter when invoking ndo_fdb_add() from rtnl_fdb_add().
