From 8fd32576e650efe88e396febd494f12adf18262a Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Tue, 20 Jun 2023 15:55:52 +0200 Subject: [PATCH] selftests: forwarding: mirror_gre_*: Use port MAC for bridge address 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 bridge eventually inherits MAC address from its first member, after the enslavement is acked. A number of (mainly VXLAN) selftests already work around the problem by setting the MAC address to whatever it will eventually be anyway. Do the same for several mirror_gre selftests.
