From 387ce1a97d703ae62032f802313113b856de303b Mon Sep 17 00:00:00 2001 From: Anjali Singhai Jain Date: Thu, 22 May 2014 06:32:23 +0000 Subject: [PATCH] i40e: Fix a bug in ethtool for FD drop packet filter action A drop action comes down as a ring_cookie value, so allow it as a special value that can be used to configure destination control. Also fix the output to filter read command accordingly.
