Date: Sat, 20 Jul 2013 12:06:57 +0900 From: Simon Horman <horms@...ge.net.au> To: dev@...nvswitch.org, netdev@...r.kernel.org Cc: Ravi K <rkerur@...il.com>, Isaku Yamahata <yamahata@...inux.co.jp>, Jesse Gross <jesse@...ira.com>, Pravin B Shelar <pshelar@...ira.com>, jarno.rajahalme@....com, Joe Stringer <joe@...d.net.nz> Subject: [PATCH v2.35 0/6] MPLS actions and matches Hi, This series implements MPLS actions and matches based on work by Ravi K, Leo Alterman, Yamahata-san and Joe Stringer. This series provides two changes * Provide user-space support for the VLAN/MPLS tag insertion order up to and including OpenFlow 1.2, and the different ordering specified from OpenFlow 1.3. In a nutshell the datapath always uses the OpenFlow 1.3 ordering, which is to always insert tags immediately after the L2 header, regardless of the presence of other tags. And ovs-vswtichd provides compatibility for the behaviour up to OpenFlow 1.2, which is that MPLS tags should follow VLAN tags if present. * Adding basic MPLS action and match support to the kernel datapath Differences between v2.35 and v2.34: * Add support for the tag ordering specified up until OpenFlow 1.2 and the ordering specified from OpenFlow 1.3. * Correct error in datapath patch's handling of GSO in the presence of MPLS and absence of VLANs. Patch overview: * The first 5 patches of this series are new, adding support for different tag ordering. * The last patch is a revised version of the patch to add MPLS support to the datapath. It has been updated to use OpenFlow 1.3 tag ordering and resolve a GSO handling bug: both mentioned above. Its change log includes a history of changes.
