Should tell here that NXM_NX_NSP is also defined, which enables
matching NSPs.
A new action is not needed to set the NSP. You can make NSP writeable
(see below), and use the existing load and move actions to set it. Also, in
OF 1.2+ you can use the standard set field action to set it as well.

If you made this "true" the "set_field", "load" and "move" actions could also
be used to set the NSP. Then the new action is not necessary at all.

The last two lines should be set to:
OFPUTIL_P_NXM_OXM_ANY,
OFPUTIL_P_NXM_OXM_ANY,
to signify that any protocol version that can encode NXM or OXM can use this
field.
