From: Huisong Li <lihuisong@huawei.com>
The error log about indirection table size during initialization phase
of PF and VF is unreasonable when the indirection table size obtained
from firmware or PF function should be zero. In addition, VF driver
should use error level to print this log.

From: Huisong Li <lihuisong@huawei.com>
The hns3_rss_set_algo_key() is used to set RSS hash algorithm and key to
hardware. The maximum times of command sent to firmware depend on the
length of key. However, now this times is fixed, which isn't good for
key expansion. In addition, hash algorithm comes from rss_info::hash_algo
maintained in driver, which also isn't good for the usage of this function.
This patch has to use hash algorithm and key length as the input parameters
of this interface.

For better compatibility, the RSS key size of PF and VF are obtained from
firmware. However, many places still used the old macro HNS3_RSS_KEY_SIZE
as the key size.

The hw::rss_info::conf::func was set to the macro RTE_ETH_HASH_FUNCTION_MAX
and hw::rss_info::conf::queue was set to NULL when all rules are flushed,
which indicates no flow rules is issued. See
commit eb158fc756a5 ("net/hns3: fix config when creating RSS rule after
flush").
Actually, the way determining whether there are rules has been changed by
walking the flow RSS list. See
commit 705a50800334 ("net/hns3: fix RSS filter restore").
In addition, the rte_flow_action_rss from user isn't saved to 'conf' in
hw->rss_info now. So this code can be removed.

When the type in 'struct rte_flow_action' is RTE_FLOW_ACTION_TYPE_RSS, the
'conf' pointer references the 'struct rte_flow_action_rss' instead of the
'struct hns3_rss_conf' in driver. But driver uses 'struct hns3_rss_conf' to
convert this 'conf' pointer to get RSS action configuration.
In addition, RSS filter configuration is directly cloned to RSS filter node
instead of coping it after successfully setting to hardware.

From: Huisong Li <lihuisong@huawei.com>
Currently, the interface for verifying duplicate RSS rules has
some problems:
1) If the value of 'func' in configuring RSS rule is default
value, this rule is mistakenly considered as a duplicate rule.
2) If key length is zero or 'key' is NULL in configuring RSS rule
this rule is also mistakenly considered as a duplicate rule.
3) If 'key' or 'queue' in struct rte_flow_action_rss being NULL
is used to memcpy, which may cause segment fault.

The error log about indirection table size during initialization phase
of PF and VF is unreasonable when the indirection table size obtained
from firmware or PF function should be zero. In addition, VF driver
should use error level to print this log.

From: Huisong Li <lihuisong@huawei.com>
The hns3_rss_set_algo_key() is used to set RSS hash algorithm and key to
hardware. The maximum times of command sent to firmware depend on the
length of key. However, now this times is fixed, which isn't good for
key expansion. In addition, hash algorithm comes from rss_info::hash_algo
maintained in driver, which also isn't good for the usage of this function.
This patch has to use hash algorithm and key length as the input parameters
of this interface.
Fixes: c37ca66f2b27 ("net/hns3: support RSS")

For better compatibility, the RSS key size of PF and VF are obtained from
firmware. However, many places still used the old macro HNS3_RSS_KEY_SIZE
as the key size.

The RSS configuration will be miscleared when driver receives a RSS rule
which has more one RSS action.

The hw::rss_info::conf::func was set to the macro RTE_ETH_HASH_FUNCTION_MAX
and hw::rss_info::conf::queue was set to NULL when all rules are flushed,
which indicates no flow rules is issued. See
commit eb158fc756a5 ("net/hns3: fix config when creating RSS rule after
flush").
Actually, the way determining whether there are rules has been changed by
walking the flow RSS list. See
commit 705a50800334 ("net/hns3: fix RSS filter restore").
In addition, the rte_flow_action_rss from user isn't saved to 'conf' in
hw->rss_info now. So this code can be removed.

The types of the rule will no longer be used when user flush all rules or
destroy a rule. But user would receive some RSS types warnings, like,
"modified RSS types based on hardware support, requested:0x137f83fffc
configured:0x3ffc".

When the type in 'struct rte_flow_action' is RTE_FLOW_ACTION_TYPE_RSS, the
'conf' pointer references the 'struct rte_flow_action_rss' instead of the
'struct hns3_rss_conf' in driver. But driver uses 'struct hns3_rss_conf' to
convert this 'conf' pointer to get RSS action configuration.
In addition, RSS filter configuration is directly cloned to RSS filter node
instead of coping it after successfully setting to hardware.

When do the below test, Segmentation fault occurred.

Segmentation fault (core dumped)
It should make sure new_conf->key is not NULL before doing memcpy.
Will fix this in V3.

From: Huisong Li <lihuisong@huawei.com>
Currently, the interface for verifying duplicate RSS rules has
some problems:
1) If the value of 'func' in configuring RSS rule is default
value, this rule is mistakenly considered as a duplicate rule.
2) If key length is zero or 'key' is NULL in configuring RSS rule
this rule is also mistakenly considered as a duplicate rule.
3) If 'key' or 'queue' in struct rte_flow_action_rss being NULL
is used to memcpy, which may cause segment fault.

The error log about indirection table size during initialization phase
of PF and VF is unreasonable when the indirection table size obtained
from firmware or PF function should be zero. In addition, VF driver
should use error level to print this log.

From: Huisong Li <lihuisong@huawei.com>
The hns3_rss_set_algo_key() is used to set RSS hash algorithm and key to
hardware. The maximum times of command sent to firmware depend on the
length of key. However, now this times is fixed, which isn't good for
key expansion. In addition, hash algorithm comes from rss_info::hash_algo
maintained in driver, which also isn't good for the usage of this function.
This patch has to use hash algorithm and key length as the input parameters
of this interface.

For better compatibility, the RSS key size of PF and VF are obtained from
firmware. However, many places still used the old macro HNS3_RSS_KEY_SIZE
as the key size.

The hw::rss_info::conf::func was set to the macro RTE_ETH_HASH_FUNCTION_MAX
and hw::rss_info::conf::queue was set to NULL when all rules are flushed,
which indicates no flow rules is issued. See
commit eb158fc756a5 ("net/hns3: fix config when creating RSS rule after
flush").
Actually, the way determining whether there are rules has been changed by
walking the flow RSS list. See
commit 705a50800334 ("net/hns3: fix RSS filter restore").
In addition, the rte_flow_action_rss from user isn't saved to 'conf' in
hw->rss_info now. So this code can be removed.

The types of the rule will no longer be used when user flush all rules or
destroy a rule. But user would receive some RSS types warnings, like,
"modified RSS types based on hardware support, requested:0x137f83fffc
configured:0x3ffc".

When the type in 'struct rte_flow_action' is RTE_FLOW_ACTION_TYPE_RSS, the
'conf' pointer references the 'struct rte_flow_action_rss' instead of the
'struct hns3_rss_conf' in driver. But driver uses 'struct hns3_rss_conf' to
convert this 'conf' pointer to get RSS action configuration.
In addition, RSS filter configuration is directly cloned to RSS filter node
instead of coping it after successfully setting to hardware.

Currently, the interface for verifying duplicate RSS rules has
some problems:
1) If the value of 'func' in configuring RSS rule is default
value, this rule is mistakenly considered as a duplicate rule.
2) If key length is zero or 'key' is NULL in configuring RSS rule
this rule is also mistakenly considered as a duplicate rule.
3) If 'key' or 'queue' in struct rte_flow_action_rss being NULL
is used to memcpy, which may cause segment fault.
