Currently, the hns3 driver uses _HNS3_XXX conditional compilation
macros to prevent duplicate header files. But in the C11 standard, all
identifiers starting with an underscore plus an uppercase letter are
always reserved. So this patch fixes it.

Current, the max waiting time for MBX response is 500ms, but in
some scenarios, it is not enough. Since it depends on the response
of the kernel mode driver, and its response time is related to the
scheduling of the system. In this special scenario, most of the
cores are isolated, and only a few cores are used for system
scheduling. When a large number of services are started, the
scheduling of the system will be very busy, and the reply of the
mbx message will time out, which will cause our PMD initialization
to fail.
This patch add a runtime config to set the max wait time. For the
above scenes, users can adjust the waiting time to a suitable value
by themselves.

Since the HW limitation for VF, the VLAN filter is default enabled, and
is not allowed to be closed. Now, the limitation has been removed in
Kunpeng930 network engine, so this patch add support for VF to modify the
VLAN filter state.
A capabilities bit is added to differentiate between different platforms
and achieve compatibility. When the VF runs on an incomatible platform or
an incompatible kernel-mode driver version is used, the VF behavior is
the same as that before.

There are some features of VF depend on PF, so it's necessary for VF
to know whether current PF supports. Therefore, the final capability
set of VF will be composed of the capability set of hardware and the
capability set of PF.
For compatibility reasons, the mailbox HNS3_MBX_GET_TCINFO has been
modified to obatin more basic information about the current PF, including
the communication interface version and current PF capabilities set.

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.

Currently, driver will copy mailbox messages body into arq ring when

message, and then call hns3_mbx_handler API which will direct process
pre-copy messages. In the whole process, the arq ring don't have a
substantial effect.
Note: The arq ring is designed for kernel environment which could not
do much job in interrupt context, but for DPDK it's not required.
Also we rename hns3_handle_link_change_event to
hns3pf_handle_link_change_event which add 'pf' suffix to make it

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.

Currently, we only support VF device is bound to vfio_pci or igb_uio and
then driven by DPDK driver when PF is driven by kernel mode hns3 ethdev
driver, VF is not supported when PF is driven by hns3 DPDK driver.
This patch adds promiscuous and allmulticast mode support for hns3 VF
PMD driver.
1) The promiscuous/allmulticast mode can be configured successfully only
based on the trusted VF device. If based on the non trusted VF
device, configuring promiscuous/allmulticast mode will fail. The hns3
VF device can be configured as trusted device by hns3 PF kernel
ethdev driver on the host by "ip link set <eth num> vf <vf id> turst
on" command.
2) After the promiscuous mode is configured successfully, hns3 VF PMD
driver can receive the ingress and outgoing traffic. In the words,
all the ingress packets, all the packets sent from the PF and other
VFs on the same physical port.
3) Note: Because of the hardware constraints, By default vlan filter is
enabled and couldn't be turned off based on VF device, so vlan filter
is still effective even in promiscuous mode. If upper applications
don't call rte_eth_dev_vlan_filter API function to set vlan based on
VF device, hns3 VF PMD driver will can't receive the packets with
vlan tag in promiscuous mode.

Currently, firmware adds the function of sending message to PF driver
through mailbox when the link status is changed, hns3 PMD driver can
usually recognize link state change faster through the message.
And in some extreme cases, this way is not faster than existing method
regularly updating link status by issuing the command every second in PF
driver, because of the parallel processing of mailbox and command
messages in firmware. So we reserve updating link status using timers in
PF driver, and add querying link status by issuing command to the
firmware in '.link_update' ops implementation function named
hns3_dev_link_update to solve the out of date link status.

When the application using VF device exits abnormally, for example,
when it is killed by 'kill -9', kernel PF netdev driver also stores
the corresponding configuration table entries of VF device.
This patch fixes it by adding message of deleting VF configuration
table entry corresponds to the revision of kernel hns3 netdev
driver, the new message is added to notify the kernel PF netdev
driver to clean up the VF configuration initialization during VF
initialization.
This revision is compatible with the old version of kernel hns3
netdev driver. The old version of kernel pf netdev driver will
