Subject: [PATCH net-next 13/16] selftests: mlxsw: qos_mc_aware: Disable IPv6 autogen on bridges
Date: Tue, 20 Jun 2023 15:55:59 +0200 [thread overview]
Message-ID: <ac5ac3c95fd19bbb9caf5544217aaae3e995afc0.1687265905.git.petrm@nvidia.com> (raw)
In-Reply-To: <cover.1687265905.git.petrm@nvidia.com>
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 (this holds
for both bridges used here), 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 traffic prioritization and scheduling,
and the bridges serve for their L2 forwarding capabilities, and do not need
to participate in routing traffic. The IP addresses or the RIFs are
irrelevant.
Fix by disabling automatic IPv6 address generation for the HW-offloaded
bridges in this selftest, thus exempting them from mlxsw router attention.
