From 08035d8e354d9fc652c9d12668e89d83edc8f974 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Tue, 20 Jun 2023 15:56:00 +0200 Subject: [PATCH] selftests: mlxsw: spectrum: q_in_vni_veto: Disable IPv6 autogen on a bridge In a future patch, mlxsw will start adding RIFs to uppers of front panel port netdevices, if they have an IP address. At the time that the front panel port is enslaved to the bridge, the bridge MAC address does not have the same prefix as other interfaces in the system. On Nvidia Spectrum-1 machines all the RIFs have to have the same 38-bit MAC address prefix. Since the bridge does not obey this limitation, the RIF cannot be created, and the enslavement attempt is vetoed on the grounds of the configuration not being offloadable. The selftest itself however checks vetoing of a different aspect of the configuration and the bridge does not need to participate in routing traffic. The IP address or the RIF are irrelevant. Fix by disabling automatic IPv6 address generation for the HW-offloaded bridge in this selftest, thus exempting it from mlxsw router attention.
