ixgbe: Add Flow Director init and modify functions for 82599
Browse files Browse the repository at this point in the history 
This patch adds the functions for ixgbe to initialize Flow Director.  It
also has the function APIs to add Flow Director filters from the base
driver.  This also includes ATR, Application Targeted Routing, which is a
feature set of Flow Director.  This is the hash-based mechanism to
automatically identify flows and add filters based on the hash, and direct
the Rx of that flow back to that same CPU.
