From 3f9e5c119a47d0fce01f8524ff0aba3acca71bb9 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Thu, 3 Oct 2019 11:49:29 +0200 Subject: [PATCH] mlxsw: spectrum_router: Don't rely on missing extack to symbolize dump Currently if info->extack is NULL, mlxsw assumes that the event came down from dump. Originally, the dump did not propagate the return value back to the original caller (fib_notifier_register()). However, that is now happening. So benefit from this and push the error up if it happened. Remove rule cases in work handlers that are now dead code. Signed-off-by: Jiri Pirko Signed-off-by: David S.
