Hi All,
I have created corresponding documentation patch for may last patch for
vf_scale.
I have noticed that there are 2 undocumented parameters: param0 and
param1, they are ready to use but missing from public documentation. I
have included them in this documentation patch.
I am not sure that it is acceptable (I mean polite) to write
documentation for other people's stuff?
please include my patch in official documentation.
thanks in advance,
best regards,
Bela Bodecs
