116e3399c0 net/hns3: remove some unused capabilities
This patch deletes some unused capabilities, include:
1. Delete some unused firmware capabilities definition, which are:
   UDP_GSO, ATR, INT_QL, SIMPLE_BD, TX_PUSH, FEC and PAUSE.
2. Delete some unused driver capabilities definition, which are:
   UDP_GSO, TX_PUSH.
3. Also redefine HNS3_DEV_SUPPORT_*  as enum type, and change some of
   the values. Note: the HNS3_DEV_SUPPORT_* values is used only inside
   the driver, so it's safe to change the values.

ca0388782c net/hns3: obtain supported speed for fiber port
Currently, the speed of fiber port is obtained by using the default
query type of HNS3_OPC_GET_SFP_INFO opcode. In this way, only
the speed of the optical module can be obtained. In fact, the opcode
also supports an active query type, which is a channel for obtaining
information such as the speed, the supported speed, auto-negotiation
capability, and FEC mode. This patch changes the query type of the
opcode from the default query type to the active query type to obtain
the supported speed of fiber port.

fb5e906940 net/hns3: support Rx descriptor advanced layout
Currently, the driver get packet type by parse the
L3_ID/L4_ID/OL3_ID/OL4_ID from Rx descriptor and then lookup multiple
tables, it's time consuming.

Now Kunpeng930 support advanced RXD layout, which:
1. Combine OL3_ID/OL4_ID to 8bit PTYPE filed, so the driver get packet
   type by lookup only one table.  Note: L3_ID/L4_ID become reserved
   fields.
2. The 1588 timestamp located at Rx descriptor instead of query from
   firmware.
3. The L3E/L4E/OL3E/OL4E will be zero when L3L4P is zero, so driver
   could optimize the good checksum calculations (when L3E/L4E is zero
   then mark PKT_RX_IP_CKSUM_GOOD/PKT_RX_L4_CKSUM_GOOD).

Considering compatibility, the firmware will report capability of
RXD advanced layout, the driver will identify and enable it by default.

This patch only provides basic function: identify and enable the RXD
advanced layout, and lookup ptype table if supported.

2e4859f3b3 net/hns3: support PF device with copper PHYs
The normal operation of devices with copper phys depends on the
initialization and configuration of the PHY chip. The task of
driving the PHY chip is implemented in some firmware versions.
If firmware supports the phy driver, it will report a capability
flag to driver in probing process. The driver determines whether
to support PF device with copper phys based on the capability bit.
If supported, the driver set a flag indicating that the firmware
takes over the PHY, and then the firmware initializes the PHY.

5ef63df128 net/hns3: fix firmware exceptions by concurrent commands
There are two scenarios that command queue uninit performed
concurrently with the firmware command: asynchronous command
and timeout command.

For asynchronous command, if a large number of functions send
commands, these commands may need to be queued to wait for
firmware processing. If a function is uninited suddenly, CMDQ
clearing and firmware processing may be performed concurrently.

For timeout command, if the command failed due to busy scheduling
of firmware, this command will be processed in the next scheduling.
And this may lead to concurrency.

The preceding concurrency may lead to a firmware exceptions.

This patch add a waiting time to ensure the firmware complete the
processing of left over command when PMD uninit.

2b6b09817d net/hns3: fix interrupt resources in Rx interrupt mode
For Kunpeng930, the NIC engine support 1280 tqps being taken over by
a PF. In this case, a maximum of 1281 interrupt resources are also
supported in this PF. To support the maximum number of queues, several
patches are made. But the interrupt related modification are missing.
So, in RX interrupt mode, a large number of queues will be aggregated
into one interrupt due to insufficient interrupts. It will lead to
waste of interrupt resources and reduces usability.

To utilize all these interrupt resources, related IMP command has been
extended. And, the I/O address of the extended interrupt resources are
different from the existing ones. So, a function used for calculating
the address offset has been added.

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.

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:

f8e7fcbfd0 net/hns3: support flow action of queue region
Kunpeng 930 hardware support spread packets to region of queues which can
be configured by FDIR rule, it means user can create one FDIR rule which
action is one region of queues, and then RSS use the region info to spread
packets.

As we know, RTE_FLOW_ACTION_TYPE_RSS is used to spread packets among
several queues, user could config such as func/level/types/key/queue
parameter to control RSS function, so we provide this feature under the
RTE_FLOW_ACTION_TYPE_RSS framework.

Consider RSS input tuple don't have eth header, we use the following
rule to distinguish them (whether it's queue region configuration or
rss general configuration):
Case 1: pattern have ETH and action's queue_num > 0, indicate it is
queue region configuration.
Case other: rss general configuration.

So if user want to configure one flow which ipv4=192.168.1.192 spread to
queue region of queue 0/1/2/3, the patter should:
  RTE_FLOW_ITEM_TYPE_ETH with spec=last=mask=NULL
  RTE_FLOW_ITEM_TYPE_IPV4 with spec=192.168.1.192 last=mask=NULL
  RTE_FLOW_ITEM_TYPE_END
the action should:
  RTE_FLOW_ACTION_TYPE_RSS with queue_num=4 queue=0/1/2/3
  RTE_FLOW_ACTION_TYPE_END
after calling rte_flow_create, one FDIR rule will be created.

992b24a1ce net/hns3: add VLAN configuration compatibility
Because of hardware limitation based on the old version of hns3 network
engine, there are some restrictions:
a) HNS3 PMD driver needs select different processing mode for VLAN based
   on whether PVID is set which means our driver need sense the PVID
   states.
b) For packets transmitting process, only two layer of VLAN tag is
   supported. If the total number of VLAN tags in mbuf and VLAN offload
   by hardware (VLAN insert by descriptor) exceeds two, the VLAN in mbuf
   will be overwritten by VLAN in the descriptor.
c) If port based VLAN is set, only one VLAN header is allowed in mbuf or
   it will be discard by hardware.

In order to solve these restriction, two change is implemented on the
new versions of network engine.
1) add a new VLAN tagged insertion mode, named tag shift mode;
2) add a new VLAN strip control bit, named strip hide enable;

The tag shift mode means that VLAN tag will shift automatically when the
inserted place has a tag. For PMD driver, the VLAN tag1 and tag2
configurations in Tx side do not need to be considered because the
hardware completes it. However, the related configuration will still be
retained to be compatible with the old version of network engine.

The VLAN strip hide means that hardware will strip the VLAN tag and hide
VLAN in descriptor (VLAN ID exposed as zero and related STRIP_TAGP is
off).

These changes make it no longer necessary for the hns3 PMD driver to be
aware of the PVID status and have the ability to send mult-layer (more
than two) VLANs packets. Therefore, hns3 PMD driver introduces the
concept of VLAN mode and adds a new VLAN mode named HNS3_PVID_MODE to
indicate that PVID-related IO process can be implemented by the
hardware. And VF driver does not need to be modified because the related
mailbox messages will not be sent by PF kernel mode netdev driver under
new network engine and all the related hardware configuration is on the
PF side.

f53a793bb7 net/hns3: add more hardware error types
The new firmware adds the hardware error types reported by MSI-x mode.

These errors are defined as RAS errors in hardware and belong to a
different type from the MSI-x errors processed by the driver.

When hardware detects an error which must be handled by the driver for
device to run properly it reports the error information through the
MSI-x interrupt. After receiving the interrupt reported by the hardware,
the driver queries the error information and identifies the error level,
then rectifies the error. All errors will be logged.
In addition, the hardware may be reset at the function or global level
based on the error level. After the reset is complete, the hardware will
recover to the normal status.

27911a6e62 net/hns3: add Rx interrupts compatibility
There are difference about queue's interrupt configurations for
different versions of hardware network engine, such as queue's interrupt
mapping mode, coalesce configuration, etc.

The following uses the configuration differences of the interrupt
mapping mode as an example.
1) For some versions of hardware network engine, such as kunpeng 920,
   because of the hardware constraint, we need implement unmmapping
   relationship configurations by binding all queues to the last
   interrupt vector and reserving the last interrupt vector. This
   results in a decrease of the maximum queues when upper applications
   call the rte_eth_dev_configure API function to enable Rx interrupt.
2) And for another versions, such as kunpeng 930, hns3 PMD driver can
   map/unmmap all interrupt vectors with queues when Rx interrupt is
   enabled.

This patch resolves configuration differences about Rx interrupts based
on kunpeng 920 and kunpeng 930.

223d9eceae net/hns3: clear residual hardware configurations on init
When the last driver exits abnormally, for example, it is killed by
'kill -9', it may be too late to clear the configuration and cause the
configuration to remain. Therefore, to ensure that the hardware
environment is clean during initialization, the PF driver actively clear
the hardware environment during initialization, including PF and
corresponding VFs' vlan, mac, flow table configurations, etc.

ef2e785c36 net/hns3: fix Tx interrupt when enabling Rx interrupt
Currently, when receiving and transmitting packets based on hns3 network
engine there are probably unexpected and redundant Tx interrupts if Rx
interrupt is enabled.

The root cause as below:
Tx and Rx queues with the same number share the interrupt vector in hns3
network engine, and in this case there are the residual hardware mapping
relationship configuration between queue and interrupt vector configured
in hns3 kernel ethdev driver.

We should clear the all hardware mapping relationship configurations in
the initialization. Because of the hardware constraints, we have to
implement clearing the relationship by binding all queues to the last
interrupt vector and reserving the last interrupt vector, this method
results in a decrease of the maximum queues when upper applications call
the rte_eth_dev_configure API function to enable Rx interrupt.
