> Currently, the flow dissector and the Flower classifier can only handle
> the first entry of an MPLS label stack. This patch series generalises
> the code to allow parsing and matching the Label Stack Entries that
> follow.
>
> Patch 1 extends the flow dissector to parse MPLS LSEs until the Bottom
> Of Stack bit is reached. The number of parsed LSEs is capped at
> FLOW_DIS_MPLS_MAX (arbitrarily set to 7). Flower and the NFP driver
> are updated to take into account the new layout of struct
> flow_dissector_key_mpls.
>
> Patch 2 extends Flower. It defines new netlink attributes, which are
> independent from the previous MPLS ones. Mixing the old and the new
> attributes in a same filter is not allowed. For backward compatibility,
> the old attributes are used when dumping filters that don't require the
> new ones.
>
> Changes since v1:
> * Fix compilation of NFP driver (kbuild test robot).
> * Fix sparse warning with entropy label (kbuild test robot).
Series applied, thanks.
