Subject: [net-next 01/12] ixgbe: remove ntuple filtering
From: Alexander Duyck <alexander.h.duyck@...el.com>
Due to numerous issues in ntuple filters it has been decided to move the
interface over to the network flow classification interface. As a first
step to achieving this I first need to remove the old ntuple interface.
