From b29a21694f7d12e40537e1e587ec47725849769b Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Wed, 11 May 2011 07:18:26 +0000 Subject: [PATCH] ixgbe: remove ntuple filtering 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.
