Onload is limited to OOF_LOCAL_ADDR_MAX number of local interface addresses. A local address can identify a physical port or a VLAN, and multiple addresses can be assigned to a single interface where each address contributes to the maximum value. Users can allocate additional local interface addresses by increasing the compile time constant OOF_LOCAL_ADDR_MAX in the /src/lib/efthrm/oof_impl.h file and rebuilding Onload. In onload-201205 OOF_LOCAL_ADDR_MAX was replaced by the onload module option max_layer2_interfaces.
