Hello everyone, we want to use external_buffer on the dpaa2 nic, but when I use rte_pktmbuf_attach, the network card cannot read the content of external_buffer correctly. When I map this external_buffer through rte_fslmc_vfio_mem_dmamap (an internal function), the network card can read the data normally, but I don’t know if there is a problem with this use (some restrictions that are not considered?). If this use is legal, I hope that developers can add dma_map and dma_unmap functions in rte_fslmc_bus, so that memory mapping can be completed by calling rte_dev_dma_map. Thank you very much.
