Involved parties looks like following: Xueming: Mellanox offloads for tunnel protocols. Adrien: rte_flow improvements for rss? Qi: rte_flow more protocol support? Declan/Awal: TEP, port representor, using rte_flow? Andrew: sfc PMD updates on top of rte_flow changes. Gaetan: devargs, previously devargs dependency mentioned for some of above, not sure that is still the case. I am not clear of latest status above patches and their dependency with eachother, are they in sync or not, it can be nice who know clarifies more. > > > [1] > Previous version in this thread is following patches: > [PATCH v4 1/2] ethdev: add supported hash function check > [PATCH v4 2/2] app/testpmd: new parameter for port config all rss command > > And this set is: > [PATCH v5 1/2] ethdev: introduce generic IP/UDP tunnel checksum and TSO > [PATCH v5 2/2] app/testpmd: testpmd support Tx generic tunnel offloads > > But there is already v5 send for this set and in other thread there is v7 of it: > [PATCH v7 0/2] support Tx generic tunnel checksum and TSO > [PATCH v7 1/2] ethdev: introduce generic IP/UDP tunnel checksum and TSO > [PATCH v7 2/2] app/testpmd: testpmd support Tx generic tunnel offloads > > Most probably you have intended to send another patchset here. >
