Fix in v19

I think there many patches wait for dmadev framework upstream, so
could you help review unreviewd patches (like dma/skeleton and app/test)?

Thanks for all the work, it looks really promising!

Also, we have developed the dma driver for hisilicon, and corresponding test
app (like examples/vhost and testpmd) is being developed.

examples/vhost: will extend support dmadev type.

I think Sunil has posted RFC for Vhost lib and example, you might want
to have a look to avoid duplicate work.

testpmd: will introduces some dma control commands and the dma forwarding mode.
         the dma forwarding mode process:
              // 1st: call rte_eth_rx_burst
              // 2st: post received packet to dma, move data to another packet
              // 3st: set newcopyed rte_mbuf header
              // 4st: free received packet
              // 5st: get dma completed request and associate it rte_mbuf
              // 6st: send 5st's rte_mbuf to nic

@Maxime @Chenbo @Xiaoyun Like to hear your opinion.

We might also think of adding async support to Vhost PMD, that would be
another way to test dmadev with testpmd.

Thanks,
Maxime

Just in case you are doing any further revisions of this patchset, the
maintainers entry, and RN entry, generally is added in the first patch, so
squash this patch into patch #1.
