4a2f6ab6fb net/hns3: fix processing link status message on PF
The opcode of the link status notification message reported by the
firmware is zero, it will be filtered out because driver treats it as
already processed message. As a result, the PF can't update the link
status in a timely manner.

Because only VF can set opcode to zero when processing mailbox message,
we add a judgment to make sure the PF messages will not be filtered out.

d345d6c957 drivers/net: fix FW version query
Fixes a few different things:
* Remove 'fw_version' NULL checks, it is allowed if the 'fw_size' is
  zero, 'fw_version' being NULL but 'fw_size' not zero condition checked
  in ethdev layer
* Be sure required buffer size is returned if provided one is not big
  enough, instead of returning success (0)
* Document in doxygen comment the '-EINVAL' is a valid return type
* Take into account that 'snprintf' can return negative value
* Cast length to 'size_t' to compare it with 'fw_size'

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.

d566bfcff0 net/hns3: fix timing in mailbox
Currently, when processing MBX messages, the system timestamp is obtained
to determine whether timeout occurs. However, the gettimeofday function
is not monotonically increasing. Therefore, this may lead to incorrect
judgment or difficulty exiting the loop. And actually, in this scenario,
it is not necessary to obtain the timestamp.

This patch deletes the call to the gettimeofday function during MBX
message processing.

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.

2. In the init stage, PF driver will detect whether firmware supports

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.

	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.

Therefore, the link status consistency between the hardware, driver,
and framework can be ensured in this interface regardless of whether
the driver is normal or abnormal.

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.

a124f9e959 net/hns3: add runtime config to select IO burst function
Currently, the driver support multiple IO burst function and auto
selection of the most appropriate function based on offload
configuration.

Most applications such as l2fwd/l3fwd don't provide the means to
change offload configuration, so it will use the auto selection's io
burst function.

This patch support runtime config to select io burst function, which
add two config: rx_func_hint and tx_func_hint, both could assign
vec/sve/simple/common.

The driver will use the following rules to select io burst func:
a. if hint equal vec and meet the vec Rx/Tx usage condition then use the
   neon function.
b. if hint equal sve and meet the sve Rx/Tx usage condition then use the
   sve function.
c. if hint equal simple and meet the simple Rx/Tx usage condition then
   use the simple function.
d. if hint equal common then use the common function.
e. if hint not set then:
e.1. if meet the vec Rx/Tx usage condition then use the neon function.
e.2. if meet the simple Rx/Tx usage condition then use the simple
     function.
e.3. else use the common function.

Note: the sve Rx/Tx usage condition based on the vec Rx/Tx usage
condition and runtime environment (which must support SVE).

In the previous versions, driver will preferred use the sve function
when meet the sve Rx/Tx usage condition, but in this case driver could
get better performance if use the neon function.

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.

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