> 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.
