I am not sure what kind of races do you mean, all libeth modules themselves are stateless and will stay this way [0], all used data is owned by drivers. As for the module separation, I think there is no harm in keeping it modular. We intend to use basic libeth (libeth_rx) in drivers that for sure have no use for libeth_cp. libeth_pci and libeth_cp separation is more arbitral, as we have no plans for now to use them separately. Module dependencies are as follows: libeth_rx and libeth_pci do not depend on other modules. libeth_cp depends on both libeth_rx and libeth_pci. idpf directly uses libeth_pci, libeth_rx and libeth_cp. ixd directly uses libeth_cp and libeth_pci.
