ffd6b0b18b net/hns3: fix VMDq mode check
HNS3 PF driver only supports RSS, DCB or NONE multiple queues mode.
Currently, driver doesn't verify the VMDq multi-queue mode completely.
This patch fixes the verification for VMDq mode.

bd7399291a net/hns3: simplify Rx checksum
Currently, the L3L4P/L3E/L4E/OL3E/OL4E fields in Rx descriptor used to
indicate hardware checksum result:
1. L3L4P: indicates hardware has processed L3L4 checksum for this
   packet, if this bit is 1 then L3E/L4E/OL3E/OL4E is trustable.
2. L3E: L3 checksum error indication, 1 means with error.
3. L4E: L4 checksum error indication, 1 means with error.
4. OL3E: outer L3 checksum error indication, 1 means with error.
5. OL4E: outer L4 checksum error indication, 1 means with error.

Driver will set the good checksum flag through packet type and
L3E/L4E/OL3E/OL4E when L3L4P is 1, it runs as follows:
1. If packet type indicates it's tunnel packet:
1.1. If packet type indicates it has inner L3 and L3E is zero, then
mark the IP checksum good.
1.2. If packet type indicates it has inner L4 and L4E is zero, then
mark the L4 checksum good.
1.3. If packet type indicates it has outer L4 and OL4E is zero, then
mark the outer L4 checksum good.
2. If packet type indicates it's not tunnel packet:
2.1. If packet type indicates it has L3 and L3E is zero, then mark the
IP checksum good.
2.2. If packet type indicates it has L4 and L4E is zero, then mark the
L4 checksum good.

As described above, the good checksum calculation is time consuming,
it impacts the Rx performance.

By balancing performance and functionality, driver uses the following
scheme to set good checksum flag when L3L4P is 1:
1. If L3E is zero, then mark the IP checksum good.
2. If L4E is zero, then mark the L4 checksum good.

The performance gains are 3% in small packet iofwd scenarios.

2192c428f9 net/hns3: fix firmware compatibility configuration
The firmware compatibility configuration in PF driver is used to
maintain the compatibility of some features of the driver and
firmware, and requires firmware to enable these features. Currently,
the configuration is in hns3_init_hardware(), which is a little back.
Because firmware may clear some configurations (such as, MAC related)
after receiving the command. And firmware can not be aware of some
default initializations (such as, flow control) before executing the
command to set the copper PHY when the PHY is controlled by firmware.
Therefore, it is recommended that no other hardware resources are
configured before the compatibility configuration. And it should be
moved to hns3_cmd_init(), which is responsible for the firmware
command initialization of driver.

In addition, the driver needs to perform corresponding processing
if the command fails to be sent.
1) If firmware fails to take over the copper PHY, the copper port fails
   to initialize.
2) If fails to enable the report of link events, the device does not
   support the LSC capability.

dbbbad23e3 net/hns3: fix VF handling LSC event in secondary process
VF will build two queues (csq: command send queue, crq: command receive
queue) with firmware, the crq may contain the following messages:
1) mailbox response message which was the ack of mailbox sync request.
2) PF's link status change message which may send by PF at anytime;

Currently, any threads in the primary and secondary processes could
send mailbox sync request, so it will need to process the crq messages
in there own thread context.

If the crq hold two messages: a) PF's link status change message, b)
mailbox response message when secondary process deals with the crq
messages, it will lead to report lsc event in secondary process
because it uses the policy of processing all pending messages at once.

We use the following scheme to solve it:
1) threads in secondary process could only process specifics messages
   (eg. mailbox response message) in crq, if the message processed, its
   opcode will rewrite with zero, then the intr thread in primary
   process will not process again.
2) threads other than intr thread in the primary process use the same
   processing logic as the threads in secondary process.
3) intr thread in the primary process could process all messages.

c8dec72de0 net/hns3: fix possible mismatched response of mailbox
Currently, the mailbox synchronous communication between VF and PF use
the following fields to maintain communication:
1. Req_msg_data which was combined by message code and subcode, used to
   match request and response.
2. Head which means the number of requests successfully sent by VF.
3. Tail which means the number of responses successfully received by VF.
4. Lost which means the number of requests which are timeout.

There may possible mismatches of the following situation:
1. VF sends message A with code=1 subcode=1.
	Then head=1, tail=0, lost=0.
2. PF was blocked about 500ms when processing the message A.
3. VF will detect message A timeout because it can't get the response
within 500ms.
	Then head=1, tail=0, lost=1.
4. VF sends message B with code=1 subcode=1 which equal message A.
	Then head=2, tail=0, lost=1.
5. PF processes the first message A and send the response message to VF.
6. VF will update tail field to 1, but the lost field will remain
   unchanged because the code/subcode equal message B's, so driver will
   return success because now the head(2) equals tail(1) plus lost(1).
   This will lead to mismatch of request and response.

To fix the above bug, we use the following scheme:
1. The message sent from VF was labelled with match_id which was a
   unique 16-bit non-zero value.
2. The response sent from PF will label with match_id which got from the
   request.
3. The VF uses the match_id to match request and response message.

This scheme depends on the PF driver, if the PF driver don't support
then VF will uses the original scheme.

f9f24ecd79 net/hns3: fix concurrent interrupt handling
Currently, if RAS interrupt and FLR occurred at the same time, FLR will
be detected and corresponding schedule state will be set during RAS
interrupt processing. However, the schedule state value will be
overridden in subsequent RAS processing, resulting in FLR processing
failure. This patch solves this problem.

7e2e162ed0 net/hns3: simplify selecting Rx/Tx function
Currently, there are four control variables (rx_simple_allowed,
rx_vec_allowed, tx_simple_allowed and tx_vec_allowed) which are used
to impact the selection of Rx/Tx burst function.

The purpose of the design is to provide a way to control the selection
of Rx/Tx burst function by modifying it's values, but these variables
have no entry to modify unless make intrusive modifications.

Now we already support runtime config to select Rx/Tx function, these
variables could be removed.

3b37cbe617 net/hns3: refactor PF LSC event report
Currently, PF driver will report lsc when it detects the link status
change, it's not a generic implementation.

We refactor PF lsc event report by following scheme:
1. PF driver marks RTE_PCI_DRV_INTR_LSC in rte_pci_driver by default.
2. In the init stage, PF driver will detect whether firmware supports
   lsc interrupt or not, driver will clear RTE_ETH_DEV_INTR_LSC flag if
   firmware doesn't support lsc interrupt.
3. PF driver will report lsc event only when dev_conf.intr_conf.lsc is
   set.

Note: If the firmware supports lsc interrupt, we also keep periodic
polling to deal with the interrupt loss.

9bc2289fe5 net/hns3: refactor VF LSC event report
Currently, VF driver periodically obtains link status from PF kernel
driver, and reports lsc event when detects link status change. Because
the period is 1 second, it's probably too late to report especially
in such as bonding scenario.

To solve this problem we use the following scheme:
1. PF kernel driver support immediate push link status to all VFs when
   it detects the link status changes.
2. VF driver will detect PF kernel driver whether support push link
   status in device init stage by sending request link info mailbox
   message to PF, PF then tell VF the push capability by extend
   HNS3_MBX_LINK_STAT_CHANGE mailbox message.
3. VF driver marks RTE_PCI_DRV_INTR_LSC in rte_pci_driver by default,
   when it detects PF doesn't support push link status then it will clear
   RTE_ETH_DEV_INTR_LSC flag.

So if PF kernel driver supports push link status to VF, then VF driver
will have RTE_ETH_DEV_INTR_LSC capability.

When FLR occurs, the head pointer register of
the command queue will be cleared, resulting in
abnormal detection of the head pointer register
of the command queue. At present, FLR is detected
in this way, and the reset recovery process is
executed.

However, when FLR occurs, the header pointer
register of the command queue is not necessarily
abnormal. For example, when the driver runs
normally, the value of the header pointer register
of the command queue may also be 0, which will
lead to the miss detection of FLR.

Therefore, the judgment that whether the base
address register of command queue is 0 is added
to ensure that FLR not miss detection.

When start testpmd with two hns3 VFs(0000:bd:01.0, 0000:bd:01.7), and
then execute the following commands:
	testpmd> create bonded device 1 0
	testpmd> set bonding mac_addr 2 3c:12:34:56:78:9a
	testpmd> add bonding slave 0 2
	testpmd> add bonding slave 1 2
	testpmd> set portmask 0x4
	testpmd> port start 2

It will occurs the following error in a low probability:
	0000:bd:01.0 hns3_get_mbx_resp(): VF could not get mbx(3,0)
		head(16) tail(15) lost(1) from PF in_irq:0
	0000:bd:01.0 hns3vf_set_default_mac_addr(): Failed to set mac
		addr(3C:**:**:**:78:9A) for vf: -62
	mac_address_slaves_update(1541) - Failed to update port Id 0
		MAC address

The problem replay:
1. The 'port start 2' command will start slave ports and then set slave
   mac address, the function call flow: bond_ethdev_start ->
   mac_address_slaves_update.
2. There are also a monitor task which running in intr thread will check
   slave ports link status and update slave ports mac address, the
   function call flow: bond_ethdev_slave_link_status_change_monitor ->
   bond_ethdev_lsc_event_callback -> mac_address_slaves_update.
3. Because the above step1&2 running on different threads, they may both
   call drivers ops mac_addr_set which is hns3vf_set_default_mac_addr.
4. hns3vf_set_default_mac_addr will first acquire hw.lock and then send
   mailbox to PF and wait PF's response message.  Note: the PF's
   response is an independent message which will received in hw.cmq.crq,
   the receiving operation can only performed in intr thread.
5. So if the step1 operation hold the hw.lock and try get response
   message, and step2 operation try acquire the hw.lock and so it can't
   process the response message, this will lead to step1 fail.

The solution:
1. make all threads could process the mailbox response message, which
   protected by the hw.cmq.crq.lock.
2. use the following rules to avoid deadlock:
2.1. ensure use the correct locking sequence: hw.lock >
     hw.mbx_resp.lock > hw.cmq.crq.lock.
2.2. make sure don't acquire such as hw.lock & hw.mbx_resp.lock again
     when process mailbox response message.

8f01e2f847 net/hns3: fix Tx checksum for UDP packets with special port
For Kunpeng920 network engine, UDP packets with destination port 6081,
4789 or 4790 will be identified as tunnel packets. If the UDP CKSUM
offload is set in the mbuf, and the TX tunnel mask is not set, the
CKSUM of these packets will be wrong. In this case, the upper layer
user may not identify the packet as a tunnel packet, and processes it
as non-tunnel packet, and expect to offload the outer UDP CKSUM, so
they may not fill the outer L2/L3 length to mbuf. However, the HW
identifies these packet as tunnel packets and therefore offload the
inner UDP CKSUM. As a result, the inner and outer UDP CKSUM are
incorrect. And for non-tunnel UDP packets with preceding special
destination port will also exist similar checksum error.

For the new generation Kunpeng930 network engine, the above errata
have been fixed. Therefore, the concept of udp_cksum_mode is
introduced. There are two udp_cksum_mode for hns3 PMD,
HNS3_SPECIAL_PORT_HW_CKSUM_MODE means HW could solve the above
problem. And in HNS3_SPECIAL_PORT_SW_CKSUM_MODE, hns3 PMD will check
packets in the Tx prepare and perform the UDP CKSUM for such packets
to avoid a checksum error.

This patch support runtime config to select io burst function, which

The driver will use the following rules to select io burst func:

1e28e842e0 net/hns3: fix imprecise statistics
Currently, the hns3 statistics may be inaccurate due to the
following two problems:

1. Queue-level statistics are read from the firmware, and only one Rx or
   Tx can be read at a time. This results in a large time interval
   between reading multiple queues statistics in a stress scenario, such
   as 1280 queues used by a PF or 256 functions used at the same time.
   Especially when the 256 functions are used at the same time, the
   interval between every two firmware commands in a function can be
   huge, because the scheduling mechanism of the firmware is similar to
   RR.

2. The current statistics are read by type. The HW statistics are read
   first, and then the software statistics are read. Due to preceding
   reasons, HW reading may be time-consuming, which cause a
   synchronization problem between SW and HW statistics of the same
   queue.

In this patch, queue-level statistics are directly read from the bar
instead of the firmware, and all the statistics of a queue include HW
and SW are read at a time to reduce inconsistency.

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.

There are two scenarios that command queue uninit performed

For asynchronous command, if a large number of functions send
commands, these commands may need to be queued to wait for

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.

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

6b978ead2b net/hns3: fix crash with multi-process
In current version, procedure of saving eth_dev in
hns3 PMD init will be called more than twice, one
for primary, the other for secondary. That will cause
segmentation fault in Multi-process as eth_dev will
be changed in secondary process, which is different
from one in primary process.

The initial problem was access to 'rte_eth_devices'
global variable, which is wrong. But current approach
can cause problem for the secondaries, moving 'eth_dev'
to process private can work but before making things
more complex.

This patch deserted the procedure of saving eth_dev in
hns3 PMD init. Instead, it creates an internal function
that gets "struct hns3_hw" as parameter and it can be
called internally without knowing 'eth_dev'and the
.dev_ops can be wrapper to this.

a1e7e04bac net/hns3: fix HW exception for unbalanced Rx/Tx queues
For kupeng 930, there are 3 registers to control the enable
status of a TQP(i.e. task queue pair, include a txq and a rxq).
One of them controls whether the TQP is enabled, and the other
two controls whether the rxq and txq are enabled. The registers
used to control the enabled status of the rxq and txq are enabled
by default. Therefore, after the TQP is enabled, the rxq and txq
are enabled by default.

Currently, when the number of rxq is not equal to the number of txq, the
unused rxqs or txqs are not disabled by driver, so these unused queues
will be enabled in this situation.  And the related HW rings have not
been initialized which could lead to a hardware exception.

This patch fix it by disable these unused queues during enable the TQPs.

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.

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.

5e76dfc33f net/hns3: fix RSS max queue id allowed in multi-TC
Currently, driver uses the maximum number of queues configured by user
as the maximum queue id that can be specified by the RSS rule or the
reta_update api. It is unreasonable and may trigger an incorrect
behavior in the multi-TC scenario. The driver must ensure that the queue
id configured in the redirection table must be within the range of the
number of queues allocated to a TC.

Implement the available and used rxd number count function.

In Kunpeng series, the NIC hardware supports to read the bd numbers
which wait processed from the hardware FBD (Full Buffer Descriptor),
and the driver maintains the bd number to be written back hardware.
Compare the number of FBDs with the number of BDs to be written back to

The number of used descriptors of a rx queue is computed as follows:
The fbd numbers of reading from FBD register plus the bd numbers to be

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.

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

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.

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

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.

that VFs no longer exist.

When PF device is in FLR reset stage, at this time, the register state

is not carried out in PF FLR.

In this case, we just ignore the register states to avoid accessing
nonexistent register and return false in the internal function named

c1ecff85d1 net/hns3: fix deleting default VLAN from PF
Currently, the default VLAN (vlan id 0) will never be deleted from the
hardware VLAN table based on hns3 PF device. As a result, even a
non-zero PVID is set by calling rte_eth_dev_set_vlan_pvid based on hns3
PF device, packets with VLAN 0 and without VLAN are still received by PF
driver in Rx direction.

This patch deletes the restriction that VLAN 0 cannot be removed in PVID
configuration to ensure packets without PVID will be filtered when PVID
is set. And the patch adds VLAN 0 to the soft list when initializing
vlan configuration to ensure that VLAN 0 will be deleted from the

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.

0134a5c7b4 net/hns3: fix crash when Tx multiple buffer packets
Currently, there is a possibility that segment faults occur when sending
packets whose payloads are stored in multiple buffers based on hns3
network engine. The related core dump information as follows:

Program terminated with signal 11, Segmentation fault.
0  hns3_reassemble_tx_pkts
2512                            temp = temp->next;
Missing separate debuginfos, use:
(gdb) bt

8  0x0000ffffa6f7fc48 in start_thread
9  0x0000ffffa6ed1600 in thread_start

The root cause is that hns3 PMD driver invokes the rte_pktmbuf_free_seg
API function to release the same rte_mbuf multiple times. The rte_mbuf
pointer is not set to NULL in the internal function
hns3_rx_queue_release_mbufs which is invoked during queue setup, stop
and close. As a result the rte_mbuf in Rx queues will be repeatedly
released when the user application setup queues or stop/start the dev
for multiple times.
Probably for performance reasons, DPDK mempool lib does not check for
the repeated rte_mbuf releases. The Address of released rte_mbuf are
directly stored into the per lcore cache of the mempool. This makes the
rte_mbufs obtained from mempool by calling rte_mempool_get_bulk API
function repetitively.  ultimately, it causes to access to a NULL
pointer in PMD driver.

This patch fixes this problem by setting released mbuf pointer to NULL
in the internal function named hns3_rx_queue_release_mbuf. And the other
internal function named hns3_reassemble_tx_pkts is optimized to avoid a
similar problem.

If the input MTU is increased and the maximum length of received packets

network engine needs to use multiple BDs and buffers to store these
packets. This will cause problems when still using vector Rx process
function or simple Rx function to receiving packets. So, when Rx of

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.

fc9b57ff57 net/hns3: fix inserted VLAN tag position in Tx
Based on hns3 network engine, in order to configure hardware VLAN insert
offload in Tx direction, PMD driver reads the VLAN tags from the
vlan_tci_outer and vlan_tci of the structure rte_mbuf, fills them into
the Tx Buffer Descriptor and sets the related offload flag for every
packet.

Currently, there are two VLAN related problems in the 'tx_pkt_burst' ops
implementation function:
1) When setting the related offload flag, PMD driver inserts the VLAN
   tag into the position that close to L3 header. So, when upper
   application sends a packet with a VLAN tag in the data buffer, the
   VLAN offloaded by hardware will be added to the wrong position. It is
   supposed to add the VLAN tag from the rte_mbuf to the position close
   to the MAC header in the packet when using VLAN insertion.

   And when PF PVID is enabled by calling the API function named
   rte_eth_dev_set_vlan_pvid or VF PVID is enabled by hns3 PF kernel
   ether driver, the VLAN tag from the structure rte_mbuf to enable the
   VLAN insertion should be filled into the position that close to L3
   header to avoid to be overwritten by the PVID which will always be
   inserted in the position that close to the MAC address.

2) When sending multiple segment packets, VLAN information is required
   to be filled into the first Tx Buffer descriptor. However, currently
   hns3 PMD driver incorrectly placed it in the last Tx Buffer
   Descriptor. This results in VLAN insert offload failure when sending
   multiple segment packets.

This patch fixed them by filling the VLAN information into the position
of the Tx Buffer Descriptor.

6c44219f99 net/hns3: fix reassembling multiple segment packets in Tx
Because of the hardware constraints, hns3 network engine doesn't support
sending packets with more than eight fragments. And hns3 pmd driver
tries to reassemble these kind of packets to meet hardware requirements.
Currently, there are two problems:
1) when the input buffer_len * 8 < pkt_len, the packets are impossible
   to be reassembled into 8 Buffer Descriptors. In this case, the

   hardware reset.
2) The meta data in origin packets which are required to fill into the

This patch adds a check for 1) to ensure such packets will be dropped by

b4e4d7ac9f net/hns3: support setting VF PVID by PF driver
This patch adds support setting VF PVID by hns3 PF kernel ethdev driver
on the host by "ip link set <eth num> vf <vf id> vlan <vlan tag>"
command.

Because of the hardware constraints, the striped VLAN tag will always in
Rx descriptors which should has been dropped when PVID is enabled and
the PVID will overwrite the outer VLAN tag in Tx descriptor. So, hns3
PMD driver need to change the processing of VLAN tags in the process of
Tx and Rx according to whether PVID is enabled.
1) If the hns3 PF kernel ethdev driver sets the PVID for VF device
   before the initialization of the related VF device, hns3 VF PMD
   driver should get the PVID state from PF driver through mailbox and
   update the related state in txq and rxq maintained by hns3 VF driver
   to change the process of Tx and Rx.
2) If the hns3 PF kernel ethdev driver sets the PVID for VF device after
   initialization of the related VF device, the PF driver will notify VF
   driver to update the PVID state. The VF driver will update the PVID
   configuration state immediately to ensure that the VLAN process in Tx
   and Rx is correct. But in the window period of this state transition,
   packets loss or packets with wrong VLAN may occur.
3) Due to hardware limitations, we only support two-layer VLAN hardware
   offload in Tx direction based on hns3 network engine, so when PVID is
   enabled, QinQ insert is no longer supported. And when PVID is
   enabled, in the following two cases:
     i) packets with more than two VLAN tags.
     ii) packets with one VLAN tag while the hardware VLAN insert is
         enabled.
   The packets will be regarded as abnormal packets and discarded by
   hardware in Tx direction. For debugging purposes, a validation check
   for these types of packets is added to the '.tx_pkt_prepare' ops
   implementation function named hns3_prep_pkts to inform users that
   these packets will be discarded.

related logs as below:
"Preparing packet burst to failed: Invalid argument"

The hardware doesn't support transmit packets less than 60 bytes, and in
the '.tx_pkt_burst' ops implementation function named hns3_xmit_pkts
appending operation has been added for less than 60 bytes packets. So
the interception needs to be removed in the '.tx_pkt_prepare' ops
implementation function named hns3_prep_pkts.

3f28ec4a88 net/hns3: clear promiscuous on PF uninit
Currently, promiscuous mode configuration are not cleared during
uninstallation based on hns3 PF device. The residual entries may cause
unnecessary bandwidth usage.

So, we need clear the PF's promisc mode status during the uninit.

e7eb703f8b net/hns3: replace special vport ids with macros
In hns3 PMD driver, the vport id 0 denote PF, and the vport id 1 denote
the first VF device of the port.

This patch adds two macros named HNS3_PF_FUNC_ID and
HNS3_1ST_VF_FUNC_ID, and replaces this two numbers to improve code
readability.

68ca93e31c net/hns3: fix return value when clearing statistics
Since the return value of the '.stats_reset' and '.xstats_reset'
callback function is int, when failing to issue command to firmware to
execute clear statistics, the relevant callback function should return
non-zero value.
