Overall patchset is good, but there is a build error in this patch [1] because
'rte_pci' library not linked with vhost library.
Fixing it while merging [2], but since this function is removed in the next
patch the changes are taken back in next patch, so the result of the patchset
should be exact same, please double check.

vdpa.c:(.text+0x9f): undefined reference to `rte_pci_addr_parse'
