adds flow in the flow table. right?

I was thinking that since open Vswitch uses 'flow_mode' struct, the
controller applications should also play around with this struct. The
controller applications sholuld put some values in "flow_mod *fm" and send
it back to the switch. The switch then receive this struct as argument of
add_flow() and add the flow in his flow table.
Now problem is that most of the controller applications, which I have seen,
play around with struct "struct ofp_flow_mod *ofm" instead of "struct
flow_mod". Is the open vSwitch code, internally convert the "ofp_flow_mod
*ofm" to "flow_mod *fm"? And then call add_flow function with 'flow_mod'
struct. Is it safe to use ofp_flow_mod in controller applications and then
use flow_mod at switch side for adding flows.

Thanks
