[ovs-dev] PORTING.md: dpif's and wildcarding

[Zoltan Kiss]

Hi,

This documentation talks a great deal about porting strategies, and it 
mentions that "Only an ofproto provider can take full advantage of 
hardware with built-in support for wildcards"
I wonder if it's still true, as dpif providers can use megaflows now, 
which are essentially wildcarding. Generally I think this file would 
worth an update from the core developers, as things might have changed 
since it's last modification.

Regards,

Zoltan
