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.

v2: added trace point to flow insertion by index functions.

Alexander Kozyrev (7):
  ethdev: add insertion by index with pattern
  app/testpmd: add index with pattern insertion type
  ethdev: add flow rule insertion by index with pattern
  app/testpmd: add insertion by index with pattern option
  ethdev: add jump to table index action
  app/testpmd: add jump to table index action
  ethdev: add trace points to flow insertion by index
