This series adds support for driver level TSO in the dpaa2-eth driver. The first 5 patches lay the ground work for the actual feature: rearrange some variable declaration, cleaning up the interraction with the S/G Table buffer cache etc. The 6th patch adds the actual driver level software TSO support by using the usual tso_build_hdr()/tso_build_data() APIs and creates the S/G FDs. With this patch set we can see the following improvement in a TCP flow running on a single A72@2.2GHz of the LX2160A SoC: before: 6.38Gbit/s after: 8.48Gbit/s Ioana Ciornei (7): dpaa2-eth: rearrange variable declaration in __dpaa2_eth_tx dpaa2-eth: allocate a fragment already aligned dpaa2-eth: extract the S/G table buffer cache interaction into functions dpaa2-eth: use the S/G table cache also for the normal S/G path dpaa2-eth: work with an array of FDs dpaa2-eth: add support for software TSO soc: fsl: dpio: read the consumer index from the cache inhibited area .../net/ethernet/freescale/dpaa2/dpaa2-eth.c | 343 ++++++++++++++---- .../net/ethernet/freescale/dpaa2/dpaa2-eth.h | 18 + .../ethernet/freescale/dpaa2/dpaa2-ethtool.c | 2 + drivers/soc/fsl/dpio/qbman-portal.c | 8 +- 4 files changed, 301 insertions(+), 70 deletions(-)
