From fa14e0a603e28eb37aa0e3857d598e1bff005466 Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Mon, 26 Oct 2020 11:42:21 +0100 Subject: [PATCH] ibmveth: Fix use of ibmveth in a bridge. [ Upstream commit 2ac8af0967aaa2b67cb382727e784900d2f4d0da ] The check for src mac address in ibmveth_is_packet_unsupported is wrong. Commit 6f2275433a2f wanted to shut down messages for loopback packets, but now suppresses bridged frames, which are accepted by the hypervisor otherwise bridging won't work at all.
