Subject: [dpdk-dev] [PATCH v4 2/7] lib/librte_ether: support l2 tunnel config
Date: Thu, 18 Feb 2016 10:46:08 +0800 [thread overview]
Message-ID: <1455763573-2867-3-git-send-email-wenzhuo.lu@intel.com> (raw)
In-Reply-To: <1455763573-2867-1-git-send-email-wenzhuo.lu@intel.com>
Add functions to support l2 tunnel configuration.
The support includes ether type modification and the tunnel support
enabling/disabling.
Ether type modification means modifying the ether type of a specific
type of tunnel. So the packet with this ether type will be parsed as
this type of tunnel.
Enabling/disabling a tunnel support means enabling/disabling the
ability of parsing the specific type of tunnel. This ability should
be enabled before we enable filtering, forwarding, offloading for
this specific type of tunnel.
Only support e-tag tunnel now.
