Commit Message

Simei Su Sept. 19, 2019, 5:15 a.m.
The v3 patch adds configuration for pppoe/pppod with input set
Source MAC and Session ID in the initialization. It also updates
release notes and Makefile/meson.build.

This patch supports the following features:
  (1)inner header hash for tunnel packets, including comms package.
  (2)symmetric hash by rte_flow RSS action.
  (3)input set change by rte_flow RSS action.

Signed-off-by: Simei Su <simei.su@intel.com>

This patch depends on the following patches on patchwork:
  (1)net/ice: rework for generic flow enabling
  (2)https://patchwork.dpdk.org/patch/57137/
      [v2,1/2] ethdev: add symmetric toeplitz hash support
  (3)https://patchwork.dpdk.org/patch/57138/
      [v2,2/2] app/testpmd: add symmetric toeplitz hash support
  (4)https://patchwork.dpdk.org/patch/57601/
      [1/2] ethdev: extend RSS offload types
  (5)https://patchwork.dpdk.org/patch/57602/
      [2/2] app/testpmd: add RSS offload types extending support
