[PATCH 01/16] net/hns3: fix possible truncation of hash key when config

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

The hash key length of hns3 driver is obtained from firmware. If the
length isn't a multiple of HNS3_RSS_HASH_KEY_NUM (16), the last part
of hash key will be truncated.

[PATCH 02/16] net/hns3: fix possible truncation of redirection table

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

The size of the redirection table is obtained from firmware. If the size
isn't a multiple of HNS3_RSS_CFG_TBL_SIZE, the redirection table from
user will be truncated.

[PATCH 03/16] net/hns3: use hardware config to report hash key

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

Currently, hns3_dev_rss_hash_conf_get() interface reports RSS key from
the key maintained by driver. It's better to report the key from hardware,
which is more realistic.

[PATCH 04/16] net/hns3: use hardware config to report hash types

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

Use the configuration in hardware to report hash types instead
of data maintained in software.

[PATCH 05/16] net/hns3: use hardware config to report redirection table

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

Currently, reta_query() API reports the redirection table from software.
This patch uses the one in hardware to report.

[PATCH 06/16] net/hns3: separate the setting of hash algorithm

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

Currently, the setting of hash algorithm comes from the
default configuration in driver and the rte_flow interface.
The hash algorithm that is set to hardware in both ways is
saved in hw->rss_info.conf.func.

But the 'func' in struct rte_flow_action_rss is usually used
in rte flow interface. And the ethdev ops interface may also
set hash algorithm in the future. It is not appropriate and
is a little messy for ethdev ops interface and driver default
configuration to use struct rte_flow_action_rss. So we have
to separate the RSS configuration from ethdev ops and rte
flow interface to make codes more easier to maintain.

This patch separates hash algorithm by following ways:
1) 'hash_algo' in struct hns3_rss_conf is used for ethdev ops
   interface or default configuration in driver.
2) Add a 'rte_flow_hash_algo' field in struct hns3_rss_conf
   to save algorithm from rte flow interface. The main reasons
   are as follows:
   Currently, only the last rule is used to restore the rte
   flow rule. If 'func' in RSS action is 'DEFAULT', it means
   that this rule doesn't modify algorithm and driver need to
   save current algorithm for restoring algorithm during reset
   phase.

[PATCH 07/16] net/hns3: separate the setting of hash key

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

The settings of hash key comes from the ethdev ops (like, dev_configure
and rss_hash_update) and rte_flow API. For the ethdev ops, driver has
to save it to rss_info::key in hns3_hw structure so as to it can be
restored when reset is triggered. While rte_flow API no need to use
this field to save, they has a global flow_rss_list to maintain all
rules which save hash key. And hash key can be restored by this rule
information during the reset phase.

[PATCH 08/16] net/hns3: separate the setting of redirection table

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

The settings of redirection table comes from the ethdev ops (like,
dev_configure and rss_hash_update) and rte_flow API. For the ethdev
ops, driver has to save it to rss_info::rss_indirection_tbl in hns3_hw
structure so as to it can be restored when reset is triggered.
While rte_flow API no need to use this field to save, they has a global
RSS flow list to maintain all rules which can be used to restore the
table during the reset phase.

[PATCH 11/16] net/hns3: use new RSS rule to configure hardware

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

Remove redundant assignment and directly use new RSS rule to configure
hardware. Additionally, considering that the new rule configuration may
need to be modified, the 'const' of input parameter about it is removed.

[PATCH 13/16] net/hns3: adding queue buffer size hash rule allowed

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

The maximum queue number from RSS flow rule allowed depends on
the maximum queue number (512) under one TC instead of the one
of Rx/Tx queue so as to eliminate restrictions on user usage.

[PATCH 14/16] net/hns3: separate rte flow RSS config from hns3 rss conf

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

Some RSS fields in struct hns3_rss_conf (e.g. conf, queue,
valid) are only used when create RSS flow rule, which is
unnecessary for RSS configuration information from ethdev
ops. This patch removes these fields from hns3_rss_conf
and add a new struct hns3_flow_rss_conf as rte flow
RSS filter list node element.

[PATCH 15/16] net/hns3: reimplement hash flow function

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

Currently, hns3 driver supports setting mulitiple rte flow RSS rule,
but only the last is valid. This implementation is different from
the mainstream usage of rte flow hash in the community. Please see
the discussion threads [1] and [2].

This patch sets RSS hash feature completely based on the request of
the flow rule so that multiple hash rules can take effect at the same
time. Please notice that:
1. For hns3, 'func' has only one hardware. 'key' and 'queue' have only
   one entry in hardware.
2. the overlapping part of the old rule will be overridden if the
   configuration items of a new rule overlap with those of an old rule.

The hns3_flow_validate() verifies and parses RSS or Fdir rules from
user, and saves them to a local variable at the same time. The local
variable is directly used to create RSS or Fdir rules. In this way,
we save one parsing and saving process.

[PATCH 16/16] net/hns3: add the verification of RSS types

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

Add the verification of RSS types from ethdev ops and rte flow without
pattern attribute. The following cases are invalid:
1. types contains unsupported RSS type but hasn't type driver support.
2. types has L3 src/dst but hasn't supported packet type.
3. types has L4 src/dst but hasn't supported packet type and hasn't IP
   packet type.

Fixes: 13c3993240c8 ("net/hns3: add L3 and L4 RSS types")

I am not sure if the explanation is correct, according below code last
part of the key is truncated if key_len *is* multiple of
HNS3_RSS_HASH_KEY_NUM.

Because code assumes "key_len % HNS3_RSS_HASH_KEY_NUM" will give the
remaining part of the key, but when key_len is multiple of
HNS3_RSS_HASH_KEY_NUM it gives 0, causing last HNS3_RSS_HASH_KEY_NUM
chunk truncated.

If above understanding correct, I can fix commit log while merging.

I am not sure if `c37ca66f2b27 ("net/hns3: support RSS")` is needed
here, issue seems because of commit 4a7384e3c34d, so this should be:

Agree that it is not ideal to have two different ways for same/similar
control path functionality in ethdev.

+Ori to discuss if this is a common problem and can be resolved in
ethdev layer.


I can see some of remaining patches are related to this ethdev / flow
API RSS separation. I will continue with this set, but I believe it is
better if this issue addressed in higher level.

This patchset is aimed to decouple the configuration API and the 
structure used by
ethdev ops and rte flow API in driver. I think this can be ignored.

As far as I know, the priority of rte flow hash rule is higher than 
ethdev ops by default,
and there are many other rules.
But the implementation guide documentation about it is not clear.
It may be better if we can clarify the documentation to guide driver coding.

I am not aware of any priority between flow API hash rule and ethdev
APIs, Ori & Andrew may comment better. And +1 to document this.
