[ovs-dev] [PATCH v3 08/12] ofp-parser: instruction parser

[Joe Stringer]

Regarding the translation of OF1.1+ instructions to vendor extensions
on OF1.0, do we want to move towards using the above syntax for
packet-out as well? (in a new patch, presumably)

We've discussed in the metadata thread, that we want to guarantee a
maximum of one write_metadata action appearing at the correct position
in the input:-

The above patch seems to solve this problem for all instructions,
although not currently for the packet-out case. This would also need
to be considered for groups/ofp_bucket.
