[dpdk-dev] [RFC PATCH 2/7] lib/librte_vhost: Add an abstraction layer for vhost backends

Tetsuya Mukawa mukawa at igel.co.jp
Thu Nov 6 12:14:26 CET 2014


The patch adds an abstraction layer for vhost backends.
So far CUSE is the only one vhost backend. But QEMU-2.1 can have one
more backend called vhost-user. To handle both backends, this kind of
layer is needed.
