80ec1bbd5b net/hns3: fix queue state after reset
FLR operation will reset the queue enabling state and
the driver needs to restore the state after reset.
If the driver does not restore the state, it will result
in unpredictable behavior with reset when user start or
stop queue by calling the relevant function if.

This patch fix it by add a queue enabling state restore
function to the reset handler.

d55f3d9c1a net/hns3: fix configurations of port-level scheduling rate
Scheduling rate of port-level in hns3 PF driver configured to
hardware is obtained from firmware, which determines the
bandwidth capability of the port. The rate in firmware is
generally configured with the maximum value for network engine
supporting multiple rates, such as 10G and 25G. It may cause
the following issues:
1) When a 10G optical module is used on the network engine, scheduling
   rate of this port will also be configured to hardware with 25G.
   However, the MAC rate of this port is 10G. In this case, it is
   unreasonable that the port scheduling rate is different from the MAC
   rate.
2) If default speed in firmware is not the maximum value, the 25G port
   may not reach the capability of the port.

Therefore, we fix configurations of port-level scheduling rate
according to updating of MAC link speed.

f9edada651 net/hns3: fix Tx checksum outer header prepare
Currently, there are two mistakes in Tx checksum outer header prepare.
1) Check whether the packet outer header is IPV4 based on PKT_TX_IPV4
   which is incorrect.
2) For HIP08, the outer UDP cksum could not be offloaded. And driver
   should ensure the outer udp cksum filed set to 0. In current code,
   PKT_TX_UDP_CKSUM is used to determine whether the outer layer of
   the packet is a UDP header. Actually, for tunnel TSO, the flag will
   never be set.

For the first mistake, it is fixed by replacing PKT_TX_IPV4 with
PKT_TX_OUTER_IPV4. And the protocol number in L3 header is used to check
whether the outer L4 header is UDP.

0e98d5e6d9 net/hns3: fix packet type report in Rx
Currently, hns3 supports recognizing a lot of ptypes, but most
tunnel packet types are not reported to the API
rte_eth_dev_get_supported_ptypes.

And there are some errors in L2 and L3 packet recognition. The
ARP and LLDP are classified to L3 field in RX descriptor. So,
the ptype of LLDP and ARP packets will be set twice. And ptypes
are assigned by bitwise OR, which will eventually cause the ptype
result to be incorrect.

Besides, when a packet with only L2 header, its ptype will not
report by hns3 PMD. This is because the L2/L3 ptype table is not
initialized properly. In this case, the table query result is 0
by default.

As a result, it fixes missing supported ptypes and the mistake in
L2/L3 packet recognition and the unreported L2 packet ptype by
reporting its L2 type when the L3 type unrecognized..

f30e69b41f ethdev: add device flag to bypass auto-filled queue xstats
Queue stats are stored in 'struct rte_eth_stats' as array and array size
is defined by 'RTE_ETHDEV_QUEUE_STAT_CNTRS' compile time flag.

As a result of technical board discussion, decided to remove the queue
statistics from 'struct rte_eth_stats' in the long term.

Instead PMDs should represent the queue statistics via xstats, this
gives more flexibility on the number of the queues supported.

Currently queue stats in the xstats are filled by ethdev layer, using
some basic stats, when queue stats removed from basic stats the
responsibility to fill the relevant xstats will be pushed to the PMDs.

During the switch period, temporary 'RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS'
device flag is created. Initially all PMDs using xstats set this flag.
The PMDs implemented queue stats in the xstats should clear the flag.

When all PMDs switch to the xstats for the queue stats, queue stats
related fields from 'struct rte_eth_stats' will be removed, as well as
'RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS' flag.
Later 'RTE_ETHDEV_QUEUE_STAT_CNTRS' compile time flag also can be
removed.

b8f5d2ae75 ethdev: remove forcing stopped state upon close
When closing a port, it is supposed to be already stopped,
and marked as such with "dev_started" state zeroed by the stop API.

Resetting "dev_started" before calling the driver close operation
was hiding the case of not properly stopped port being closed.
The flag "dev_started" is not changed anymore in "rte_eth_dev_close()".

In case the "dev_stop" function is called from "dev_close",
bypassing "rte_eth_dev_stop()" API,
the "dev_started" state must be explicitly reset in the PMD
in order to keep the same behaviour.

76d794566d net/hns3: maximize queue number
The maximum number of queues for hns3 PF and VF driver is 64 based on
hns3 network engine with revision_id equals 0x21. Based on hns3 network
engine with revision_id equals 0x30, the hns3 PF PMD driver can support
up to 1280 queues, and hns3 VF PMD driver can support up to 128 queues.

The following points need to be modified to support maximizing queue
number and maintain better compatibility:
1) Maximizing the number of queues for hns3 PF and VF PMD driver In
   current version, VF is not supported when PF is driven by hns3 PMD
   driver. If maximum queue numbers allocated to PF PMD driver is less
   than total tqps_num allocated to this port, all remaining number of
   queues are mapped to VF function, which is unreasonable. So we fix
   that all remaining number of queues are mapped to PF function.

   Using RTE_LIBRTE_HNS3_MAX_TQP_NUM_PER_PF which comes from
   configuration file to limit the queue number allocated to PF device
   based on hns3 network engine with revision_id greater than 0x30. And
   PF device still keep the maximum 64 queues based on hns3 network
   engine with revision_id equals 0x21.

   Remove restriction of the macro HNS3_MAX_TQP_NUM_PER_FUNC on the
   maximum number of queues in hns3 VF PMD driver and use the value
   allocated by hns3 PF kernel netdev driver.

2) According to the queue number allocated to PF device, a variable
   array for Rx and Tx queue is dynamically allocated to record the
   statistics of Rx and Tx queues during the .dev_init ops
   implementation function.
3) Add an extended field in hns3_pf_res_cmd to support the case that
   numbers of queue are greater than 1024.
4) Use new base address of Rx or Tx queue if QUEUE_ID of Rx or Tx queue
   is greater than 1024.
5) Remove queue id mask and use all bits of actual queue_id as the
   queue_id to configure hardware.
6) Currently, 0~9 bits of qset_id in hns3_nq_to_qs_link_cmd used to
   record actual qset id and 10 bit as VLD bit are configured to
   hardware. So we also need to use 11~15 bits when actual qset_id is
   greater than 1024.
7) The number of queue sets based on different network engine are
   different. We use it to calculate group number and configure to
   hardware in the backpressure configuration.
8) Adding check operations for number of Rx and Tx queue user configured
   when mapping queue to tc Rx queue numbers under a single TC must be
   less than rss_size_max supported by a single TC. Rx and Tx queue
   numbers are allocated to every TC by average. So Rx and Tx queue
   numbers must be an integer multiple of 2, or redundant queues are not
   available.
9) We can specify which packets enter the queue with a specific queue
   number, when creating flow table rules by rte_flow API. Currently,
   driver uses 0~9 bits to record the queue_id. So it is necessary to
   extend one bit field to record queue_id and configure to hardware, if
   the queue_id is greater than 1024.

9a7d3af22c net/hns3: expand number of queues for one TC up to 512
The maximum number of queues for one TC hns3 PF PMD driver supported is
64 based on hns3 network engine with revision_id equals 0x21, while it
is expanded up to 512 on hns3 network engine with revision_id equals
0x30.

So the following points need to be modified to maintain better
compatibility.
1) Using a extended rss_size_max field as the maximum queue number of
   one TC PF driver supported.
2) The data type of the RSS redirection table needs to be changed from
   uint8_t to uint16_t.
3) rss_tc_mode modification
   The bitwidth of tc_offset, meaning the rx queue index, has to expand
   from 10 bit to 11 bits. The tc_size, meaning the exponent with base 2
   of queues supported on TC, needs to expand from 3 bits to 4 bits.
4) RSS indirection table modification
   Currently, a field with 7 bits width is used to record the queue
   index for RSS indirection table. It means that PF needs to expand the
   queue index field to 9 bits. As the RSS indirection table config
   command reserved 4 bytes to configure the RSS queue index, a extern
   field can be added. So an entries of RSS indirection table queue
   index has two fields to set: rss_result_l and rss_result_h, while
   rss_result_l records the lower 8 bits and rss_result_h records the
   higher 1 bit.

In addition, 2~4 modifications is also compatible with hns3 VF PMD
driver.

fbd1913561 ethdev: remove old close behaviour
The temporary flag RTE_ETH_DEV_CLOSE_REMOVE is removed.
It was introduced in DPDK 18.11 in order to give time for PMDs to migrate.

The old behaviour was to free only queues when closing a port.
The new behaviour is calling rte_eth_dev_release_port() which does
three more tasks:
	- trigger event callback
	- reset state and few pointers
	- free all generic port resources

The private port resources must be released in the .dev_close callback.

The .remove callback should:
	- call .dev_close callback
	- call rte_eth_dev_release_port()
	- free multi-port device shared resources

Despite waiting two years, some drivers have not migrated,
so they may hit issues with the incompatible new behaviour.
After sending emails, adding logs, and announcing the deprecation,
the only last solution is to declare these drivers as unmaintained:
	ionic, liquidio, nfp
Below is a summary of what to implement in those drivers.

* The freeing of private port resources must be moved
from the ".remove(device)" function to the ".dev_close(port)" function.

* If a generic resource (.mac_addrs or .hash_mac_addrs) cannot be freed,
it must be set to NULL in ".dev_close" function to protect from
subsequent rte_eth_dev_release_port() freeing.

* Note 1:
The generic resources are freed in rte_eth_dev_release_port(),
after ".dev_close" is called in rte_eth_dev_close(), but not when
calling ".dev_close" directly from the ".remove" PMD function.
That's why rte_eth_dev_release_port() must still be called explicitly
from ".remove(device)" after calling the ".dev_close" PMD function.

* Note 2:
If a device can have multiple ports, the common resources must be freed
only in the ".remove(device)" function.

* Note 3:
The port is supposed to be in a stopped state when it is closed.
If it is not the case, it is free to the PMD implementation
how to react when trying to close a non-stopped port:
either try to stop it automatically or just return an error.

81f04b9c20 net/hns3: fix storing RSS info when creating flow action
Currently, when calling the rte_flow_query API function to query the RSS
information, the queue related information is not as expected.

The root cause is that when application call the rte_flow_create API
function to create RSS action, the operation of storing the data whose typs
is struct rte_flow_action_rss is incorrect in the '.create' ops
implementation function named hns3_flow_create.

This patch fixes it by replacing memcpy with hns3_rss_conf_copy function to
store the RSS information in the hns3_flow_create.

fd81968387 net/hns3: fix configuring device with RSS enabled
Currently, when running the following commands in the CLI of testpmd
application, the driver reports an -EINVAL error when performing the No.3
step.
1) flow create 0 ingress pattern end actions rss key <key> func simple_xor
     types all end / end
2) flow flush 0
3) port config dcb vt off pfc off

The root cause as below:
In the No.2 step, when RSS rules is flushed, we set the the flag
hw->rss_dis_flag with true to indicate RSS id disabled. And in the No.3
step, calling rte_eth_dev_configure API function, the internal function
named hns3_dev_rss_hash_update check hw->rss_dis_flag is true and return
-EINVAL.

When user calls the rte_eth_dev_configure API function with the input
parameter dev_conf->rxmode.mq_mode having ETH_MQ_RX_RSS_FLAG to enable RSS,
driver should set internal flag hw->rss_dis_flag with false to indicate RSS
is enabled in the '.dev_configure' ops implementation function named
hns3_dev_configure and hns3vf_dev_configure.

ec674cb742 net/hns3: fix flushing RSS rule
When user create a flow without RSS by calling rte_flow_create API and then
destroy it by calling rte_flow_flush API, driver should not clear RSS rule.

A reasonable handling method is that when user creates an RSS rule, the
driver should clear the created RSS rule when flushing destroy all flow
rules. Also, hw->rss_info should save the RSS config of the last success
RSS rule. When create n RSS rules, the RSS should not be disabled before
the last RSS rule destroyed.

eb158fc756 net/hns3: fix config when creating RSS rule after flush
Currnetly, when user create a flow RSS rule and then flush the rule, driver
will set 0 for the internal structure of hw->rss_info maintained in driver.
And then user create a flow RSS rule without specified RSS hash key, driver
configure a validate RSS hash key into hardware network engine and will
cause an RSS error. The related steps when using testpmd as
follows:
  flow 0 <pattern> action rss xx end / end
  flow flush 0
  flow 0 <pattern> action rss queues 0 1 end / end

To slove the preceding problem, the flow flush processing is modified.
it don't clear all RSS configurations for hw->rss_info. Actually the RSS
key information in the hardware is not cleared, therefore, the
hw->rss_info.key is kept consistent with the value in the hardware. In
addition, because reset the redirection table, we need to set queues NULL
and queue_num for zero that indicate the corresponding parameters in the
hardware is unavailable. Also we set hw->rss_info.func to
RTE_ETH_HASH_FUNCTION_MAX that indicate it is invalid.

806f1d5ab0 net/hns3: set RSS hash type input configuration
This patch support for hash type input set configuration. That is, upper
level application can call the rte_flow_create or
rte_eth_dev_rss_hash_update API to set the specified tuples by RSS types.
As a result, the hardware can selectively use the tuples to perform hash
calculation based on the specific tuple to enable the fields.
The following uses the RSS flow as an example:

When application calls the rte_flow_create API to select tuple input for
ipv4-tcp l3-src-only, the driver can enable the ipv4-tcp src field of the
hardware register by calling the internal function named
hns3_set_rss_tuple_by_rss_hf according to the RSS types in actions list.
In testpmd application, the command as follows:
testpmd> flow create 0 ingress pattern end actions rss types \
ipv4-tcp l3-src-only end queues 1 3 end / end

The following use the rte_eth_dev_rss_hash_update as an example:
if the user set the select tuple input for ipv4-tcp l3-src-only by
rte_eth_rss_conf structure in rte_eth_dev_rss_hash_update. the next
flow is the same as that of the RSS flow. In testpmd application,
the command as follows:
testpmd> port config all rss ipv4-tcp l3-src-only
