Subject: [dpdk-stable] [PATCH v6] net/i40e: fix mirror rule reset when port is closed
Date: Mon, 25 Sep 2017 14:36:53 +0800	[thread overview]
Message-ID: <1506321413-38887-1-git-send-email-wei.dai@intel.com> (raw)
In-Reply-To: <1505881001-12200-1-git-send-email-wei.dai@intel.com>

When an i40e PF port is stopped, all mirror rules should be reserved.
But when an i40e PF port is closed, all mirror rules should be removed.
When a mirror rule is removed, its associated hardware and software
resource should also be removed.

Fixes: a4def5edf0fc ("i40e: enable port mirroring")
Cc: stable@dpdk.org
