For existing drivers this has been documented in features file as another file (another column in table), but we are looking for better representation for this. What do you think, does two drivers has significant enough differences to be documented as two different drivers? > +RTE_PMD_REGISTER_PCI_TABLE(net_nfp_pf, pci_id_nfp_pf_net_map); > +RTE_PMD_REGISTER_PCI_TABLE(net_nfp_vf, pci_id_nfp_vf_net_map); > +RTE_PMD_REGISTER_KMOD_DEP(net_nfp_pf, "* igb_uio | uio_pci_generic | vfio"); > +RTE_PMD_REGISTER_KMOD_DEP(net_nfp_vf, "* igb_uio | uio_pci_generic | vfio"); > > /* > * Local variables: >
