[PATCH v2 0/7] ethdev: jump to table support

[Alexander Kozyrev <akozyrev@nvidia.com>]

Introduce new Flow API JUMP_TO_TABLE_INDEX action.
It allows bypassing a hierarchy of groups and going directly
to a specified flow table. That gives a user the flexibility
to jump between different priorities in a group and eliminates
the need to do a table lookup in the group hierarchy.
The JUMP_TO_TABLE_INDEX action forwards a packet to the
specified rule index inside the index-based flow table.

The current index-based flow table doesn't do any matching
on the packet and executes the actions immediately.
Add a new index-based flow table with pattern matching.
The JUMP_TO_TABLE_INDEX can redirect a packet to another
matching criteria at the specified index in this case.
