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.

I don't think this function has something to do with 'log', better to use name
like ice_hash_engine_init.

What about:

	struct ice_flow_parser *parser; 

	if (ad->active_pkg_type == ICE_PKG_TYPE_OS_DEFAULT) {
		parser = &ice_hash_parser_os;
	} else if (ad->active_pkg_type == ICE_PKG_TYPE_COMMS) {

	}

	return ice_register_parser(parser, ad);

It's actually used in this function, so just remove the __rte_unused tag.

If ice_rem_vsi_rss_cfg fails here, do we still need to proceed to free the flow
other than return error here?

  I write "ice_hash_init_log" referring to other module. I also think it has nothing to do
with 'log'. Ok, I will modify it.

   It looks a good advice, can avoid unnecessary redundancy.

  Yes, it's my negligence that other than return error, also need to error out here.
I will add it in v3 patch.

  Cc: dev, simei.su

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/

[PATCH v4 1/2] add teid hash for gtupu and session id hash for pppoe/pppod.
[PATCH v4 2/2] support input set change and symmetric hash by rte_flow RSS action.

[PTACH v4 2/2] 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/59982/
       [v4,1/3] ethdev: decouple flow types and RSS offload types
  (5)https://patchwork.dpdk.org/patch/59983/
       [v4,2/3] ethdev: extend RSS offload types
  (6)https://patchwork.dpdk.org/patch/59985/
       [v4,3/2] app/testpmd: add RSS offload types extending support

v4:
* Add rss support for gtpu with teid and pppoe/pppod with session id.
* Split up into patchset.

v3:
* Modify codes according to the comments.
* Update release notes and Makefile/meson.build.

v2:
* Amend to resend patch that v1 is not in community.

[PATCH v5 1/2] add teid hash for gtupu and session id hash for pppoe/pppod.
[PATCH v5 2/2] support input set change and symmetric hash by rte_flow RSS action.

[PTACH v5 2/2] 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/60097/
       [v7,1/3] ethdev: decouple flow types and RSS offload types
  (5)https://patchwork.dpdk.org/patch/60098/
       [v7,2/3] ethdev: extend RSS offload types
  (6)https://patchwork.dpdk.org/patch/60099/
       [v7,3/3] app/testpmd: add RSS offload types extending support

v5:
* Update title for cover letter and commit log.
* Fix some code style.

v4:
* Add rss support for gtpu with teid and pppoe/pppod with session id.
* Split up into patchset.

v3:
* Modify codes according to the comments.
* Update release notes and Makefile/meson.build.

v2:
* Amend to resend patch that v1 is not in community.

[PATCH v6 1/2] add teid hash for gtupu and session id hash for pppoe/pppod.
[PATCH v6 2/2] support input set change and symmetric hash by rte_flow RSS action.

v6:
* Add simultaneous use of SRC_ONLY and DST_ONLY of the same level.
* Update cases in ice_hash_type_list[].

v5:
* Update title for cover letter and commit log.
* Fix some code style.

v4:
* Add rss support for gtpu with teid and pppoe/pppod with session id.
* Split up into patchset.

v3:
* Modify codes according to the comments.
* Update release notes and Makefile/meson.build.

v2:
* Amend to resend patch that v1 is not in community.

[PATCH v7 1/2] add teid hash for gtupu and session id hash for pppoe/pppod.
[PATCH v7 2/2] support input set change and symmetric hash by rte_flow RSS action.

v7:
* Rebase patches to solve merge conflict.

v6:
* Add simultaneous use of SRC_ONLY and DST_ONLY of the same level.
* Update cases in ice_hash_type_list[].

v5:
* Update title for cover letter and commit log.
* Fix some code style.

v4:
* Add rss support for gtpu with teid and pppoe/pppod with session id.
* Split up into patchset.

v3:
* Modify codes according to the comments.
* Update release notes and Makefile/meson.build.

v2:
* Amend to resend patch that v1 is not in community.

[PATCH v8 1/2] add teid hash for gtupu and session id hash for pppoe/pppod.
[PATCH v8 2/2] support input set change and symmetric hash by rte_flow RSS action.

v8:
* Change meta type from uint64_t to void pointer for pattern structure.
* Modify related code in ice_hash.c about above change.

v7:
* Rebase patches to solve merge conflict.

v6:
* Add simultaneous use of SRC_ONLY and DST_ONLY of the same level.
* Update cases in ice_hash_type_list[].

v5:
* Update title for cover letter and commit log.
* Fix some code style.

v4:
* Add rss support for gtpu with teid and pppoe/pppod with session id.
* Split up into patchset.

v3:
* Modify codes according to the comments.
* Update release notes and Makefile/meson.build.

v2:
* Amend to resend patch that v1 is not in community.

Simei Su (3):
  net/ice: add RSS configuration for gtpu/pppoe
  net/ice: change one member type of the pattern structure
  net/ice: enable advanced RSS

ICC is giving following error [1], it seems switch case is not a scope, so
fixing the warning while merging by moving the definitions above switch.


[1]
error #589: transfer of control bypasses initialization of:
            variable "rss_hf" (declared at line 299)
                switch (action_type) {
                ^
