useful examples during a port:
* lib/dpif-linux.c is a Linux-specific dpif implementation that
- talks to a Open vSwitch-specific kernel module (whose sources
+ talks to an Open vSwitch-specific kernel module (whose sources
are in the "datapath" directory). The kernel module performs
all of the switching work, passing packets that do not match any
- flow table entry down to userspace. This dpif implementation is
+ flow table entry up to userspace. This dpif implementation is
essentially a wrapper around calls to "ioctl".
* lib/dpif-netdev.c is a generic dpif implementation that performs
