e2a8cae024 net/hns3: fix some incomplete command structures
The descriptor of the command between firmware and driver consists of
8-byte header and 24-byte data field. The contents sent to firmware are
packaged into a command structure as the data field of command
descriptor.

There are some command structures in hns3_dcb.h file that are less than
24 byte. So this patch fixes these incomplete command structures.

6c507191d1 net/hns3: fix default MAC address from firmware
Currently, default MAC address obtained from firmware in PF driver is
directly used by .mac_addr_set ops implementation function when the
rte_eth_dev_start API function is executed. At this moment, if the
default MAC addr isn't an unicast address, it will fail to set default
MAC addr to hardware.

So this patch adds the validity check of default MAC addr in PF driver.
We will use a random unicast address, if the default MAC address
obtained from firmware is not a valid unicast address.

In addition, this patch also adjusts the location of processing default
MAC addr in VF driver so as to increase relevance and readability of the
code.

59200fd71a net/hns3: support maximum 256 flow director counter
The FDIR counter was used to count the number of FDIR hit, the maximum
number of the counter is 128 based on kunpeng 920, and it was 256 based
on kunpeng 930.

The firmware is responsible to allocate counters for different PF
devices, so the available counter number of one PF may be bigger than
128.

Currently, there are two places using the counter in driver:
1. Configure the counter. Driver uses the command whose opcode is
   HNS3_OPC_FD_AD_OP, now we extend one bit to hold the high bit of
   counter-id in the command format.
2. Query the statistic information of the counter. Driver uses the
   command whose opcode is HNS3_OPC_FD_COUNTER_OP, now the command
   already support 16-bit counter-id.

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.

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
   packets will be passed to hardware, which eventually causes a
   hardware reset.
2) The meta data in origin packets which are required to fill into the
   descriptor haven't been copied into the reassembled pkts.

This patch adds a check for 1) to ensure such packets will be dropped by
driver and copies useful meta data from the origin packets to the
reassembled packets.

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.

80cd38e1b5 net/hns3: ignore function return on reset error path
There is a coverity defect related "Unchecked return value".

The internal static hns3_reset_err_handle function is reset error
process of hns3 PMD driver. If failure in reset process, it does not
mean that the network port is completely unavailable, so the command
interface between driver and firmware still needs to be initialized.
Regardless of whether the execution of the function named hns3_cmd_init
is successful or not, the next process after execution must be
continued, so there is no need to check the return value. If
hns3_cmd_init fails to execute, there will be corresponding log
information inside hns3_cmd_init.

This patch adds '(void)' Type conversion to avoid coverity warning.

e28bc14765 net/hns3: fix VLAN tags reported in Rx
Currently, based on hns3 network engine, driver always reports the
incoming packet's VLAN tags to the structure rte_mbuf those are the
output parameter pointers in '.rx_pkt_burst' ops implementation
function, and never reports PKT_RX_VLAN_STRIPPED flag to the structure
rte_mbuf even if Upper Level Process configured hardware strip by
calling rte_eth_dev_configure or rte_eth_dev_set_vlan_offload API
function. It makes the ULP unable to know the stripping of VLAN.

It is supposed to present the stripped flags to the mbuf ol_flags, and
report the right VLAN tag.

And as hardware constraints, the stripped VLAN tag will always in the Rx
descriptor. Even if setting a PVID based on the function, the PVID will
be reported to the Rx descriptor. So the driver need to determine which
VLAN tag should be reported to output the structure rte_mbuf in
'.rx_pkt_burst' ops implementation function named hns3_recv_pkts.

4c623ca400 net/hns3: fix VLAN strip configuration when setting PVID
Currently, based on hns3 PF device, hardware will strip 2 vlan tags when
ULP calls rte_eth_dev_set_vlan_pvid API function to set a PVID whether
vlan strip related offload is turned on by calling rte_eth_dev_configure
or rte_eth_dev_set_vlan_offload API function.

When receiving a QinQ packet with the pvid tag, if ULP does not
configure the vlan strip by the method mentioned above, a layer of vlan
tag will be lost to ULP, which is not the expected result.

It is supposed to configure the vlan strip according to the upper level
process's configuration.

16c374402f net/hns3: fix Tx less than 60 bytes
Currently, when running testpmd application based on hns3 network engine
with csum fwd mode by "set fwd csum" command in the prompt line, sending
42 consecutive bytes of ARP packets to network port with packets
generator. But in fact hardware can't send the ARP packets and the
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.

2de74dcfbd net/hns3: fix MSI-X interrupt during initialization
Currently, based on hns3 VF device error may occur during initialization.

The root cause as below:
When the following formula is executed during initialization, the
private variable named hw->tqps_num has not been obtained from PF driver
through mailbox, further causes failure when mapping interrupt and
queues.
  hw->num_msi = (num_msi > hw->tqps_num + 1) ? hw->tqps_num + 1 : num_msi;
We need to use hw->tqp_num after it is correctly assigned.

On the other hand, because the private variable named hw->num_msi, which
represents the number of MSI-x interrupt of hns3 PF/VF device, is used in
the '.get_reg' ops implementation function to dump all interrupt related
registers, it should be obtained from firmware directly and we'd better
not modify it in the driver.

99d673d5d3 net/hns3: fix VLAN PVID when configuring device
In current version, when upper level application calls the
rte_eth_dev_configure API function, if pvid config is not set of the
input parameter which struct type is rte_eth_conf, hns3 pmd driver also
sets the VLAN pvid related configuration to hardware, and this is not
reasonable. For example, As pvid is set to 100 by
rte_eth_dev_set_vlan_pvid, when pvid config is not set in rte_eth_conf,
rte_eth_dev_configure will tell driver to delete pvid 0, and that is
meaningless.

This patch fixes it to ensure that driver does not set VLAN pvid related
configuration to hardware when pvid config is not set in rte_eth_conf.
