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.
