LGTM, thanks
And I'am prepare dmadev V2, include:
a) Fix code review comments (e.g. multiple-process support, doxygen, comments, typo)
b) Flatten device abstraction to two layer: dmadev <> vchan
c) Public API use dev_id and vchan_id to locate one vchan
d) Using the flags parameter instead of the fence API
e) Rename rte_dmadev_perform to rte_dmadev_submit so it corresponds to the stats variable.
PS: Some code (lib/dmadev) will rebase this patchset
