Subject: [PATCH v2.47 1/4] odp: Allow VLAN actions after MPLS actions
From: Joe Stringer <joe@...d.net.nz>
OpenFlow 1.1 and 1.2, and 1.3 differ in their handling of MPLS actions in the
presence of VLAN tags. To allow correct behaviour to be committed in
each situation, this patch adds a second round of VLAN tag action
handling to commit_odp_actions(), which occurs after MPLS actions. This
is implemented with two new fields in struct xlate_ctx,
'post_mpls_vlan_tci' and 'next_vlan_tci'.
Any modifications to the VLAN TCI by actions are made to 'next_vlan_tci'.
Initially 'next_vlan_tci' points to 'xin->flow->vlan_tci' so that VLAN
actions are committed before any MPLS actions. When an MPLS action is
composed 'next_vlan_tci' is updated to point to 'post_mpls_vlan_tci'. This
causes subsequent VLAN actions to be committed after MPLS actions.
Both before and after this patch MPLS LSEs are pushed onto a packet after
any VLAN tags that may be present. This is the behaviour described in
OpenFlow 1.1 and 1.2. OpenFlow 1.3 specifies that MPLS LSEs should be
pushed onto a packet before any VLAN tags that are present. Support
for this will be added by a subsequent patch that makes use of
the infrastructure added by this patch.

v2.47
* No change
v2.46 [Simon Horman]
* Updated changelog as it had become out of date
v2.45 [Simon Horman]
* As pointed out by Ben Pfaff and Joe Stringer
+ Update VLAN handling in the presence of MPLS push
Previously the test for committing ODP VLAN actions after MPLS actions
was that the VLAN TCI differed before and after the MPLS push action.
This results in a false negative in some cases including if a VLAN tag
is pushed after the MPLS push action in such a way that it duplicates
the VLAN tag present before the MPLS push action.
This is resolved by ensuring the VLAN_CFI bit of the value used to
track the desired VLAN TCI after an MPLS push action is zero unless
VLAN actions should be committed after MPLS actions.
+ Update tests to use ovs-ofctl monitor "-m" to allow full inspection of
MPLS LSE and VLAN tags present in packets.
v2.44 [Simon Horman]
* Rebase for the following changes:
f47ea02 ("Set datapath mask bits when setting a flow field.")
7fdb60a ("Add support for write-actions")
7358063 ("odp-util: Elaborate the comment for odp_flow_format() function.")
* Correct final_vlan_tci and next_vlan_tci initialisation in xlate_actions__()
v2.43 [Simon Horman]
* As suggested by Ben Pfaff
Move vlan state into struct xlate_ctx
1. Add final_vlan_tci member to struct xlate_ctx instead of vlan_tci member
struct xlate_xin. This seems to be a better palace for it as it does
not need to be accessible from the caller.
2. Move local vlan_tci variable of do_xlate_actions() to be the
next_vlan_tci member of strict xlate_ctx. This allows for it to work
across resubmit actions and goto table instructions.
v2.42
* No change
v2.41 [Joe Stringer via Simon Horman]
* Rework comments to make things a little clearer
v2.40 [Simon Horman]
* Rebase for removal of mpls_depth from struct flow
v2.38 - v2.39
* No change
v2.37
