The eIPoIB local Ethernet MAC is currently constructed from the port GUID. Given a base GUID/MAC value of N, Mellanox seems to populate: Node GUID: N + 0 Port 1 GUID: N + 1 Port 2 GUID: N + 2 and Port 1 MAC: N + 0 Port 2 MAC: N + 1 This causes a duplicate local MAC address when port 1 is configured as Infiniband and port 2 as Ethernet, since both will derive their MAC address as (N + 1). Fix by using the port's Ethernet MAC as the eIPoIB local EMAC. This is a behavioural change that could potentially break configurations that rely on the local EMAC value, such as a DHCP server relying on the chaddr field for DHCP reservations.
