7c9f68872d net/hns3: fix mailbox opcode data type
The mailbox opcode is defined as one byte in datasheet which is not
compatible with that in the current hns3 PMD driver.

This patch fixes the data type of the local variable for mailbox opcode
in driver, changing from uint16_t to uint8_t.

40486d3849 net/hns3: support promiscuous and allmulticast mode for VF
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.

c05e0c5b74 net/hns3: fix ring vector related mailbox command format
The format of the ring vector related mailbox commands between driver
and firmware is different from those of other mailbox commands in hns3
network engine.

This patch fixes the error mailbox command format about the vector of
the rings, the related command opcode as below:
HNS3_MBX_MAP_RING_TO_VECTOR
HNS3_MBX_UNMAP_RING_TO_VECTOR
HNS3_MBX_GET_RING_VECTOR_MAP

109e4dd1bd net/hns3: get link state change through mailbox
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.

e4eae34a8c net/hns3: fix mailbox response length
Remove the macro 'HNS3_REG_MSG_DATA_OFFSET' which is used to prevent
access violation for response array by limiting the response data length
to 4.
But the limit value is too short to get some longer information such as
6 byte MAC address.

This patch modifies the length of response data from mailbox to allow
the response data length to be 8. So that the VF driver could get more
data from PF driver by mailbox.

2790c64647 net/hns3: support device reset
This patch adds reset related process for hns3 PMD driver.
The following three scenarios will trigger the reset process,
and the driver settings will be restored after the reset is
successful:
1. Receive a reset interrupt
2. PF receives a hardware error interrupt
3. VF is notified by PF to reset
