So far all features we added required explicit driver support.
Checksumming support as an example will require driver changes, too.
Generalized way to call programs is probably not going to buy us much?
 

Hi Jakub,

What is the the concern with checksumming? Isn't that just an issue of
defining fields in xdp_data and driver populating with the appropriate
information?

Thanks for replying!  I was just using checksumming as an example.  I
was trying to counter the argument that the hook infrastructure will
allow for features to be implemented mostly transparently to the
drivers.  I may be wrong but it seems that it doesn't buy us anything
as far as the features which were so far discussed go.
