drivers require uio/vfio.\n\nSigned-off-by: Olivier Matz <olivier.matz@6wind.com>\nAcked-by: Fiona Trahe <fiona.trahe@intel.com>\n---\n\nv1 -> v2: \n- do not advertise uio_pci_generic for vf drivers\n- rebase on top of head: use new driver names and prefix\n macro with RTE_ \n\nrfc -> v1:\n- the kmod information can be per-device using a modalias-like\n pattern\n- change syntax to use '&' and '|' instead of ',' and ':'\n- remove useless prerequisites in kmod lis: no need to\n specify both uio and uio_pci_generic, only the latter is\n required\n- update kmod list in szedata2 driver\n- remove kmod list in qat driver: it requires more than just loading\n a kmod, which is described in documentation\n\n\n buildtools/pmdinfogen/pmdinfogen.c | 1 +\n buildtools/pmdinfogen/pmdinfogen.h | 1
