b25987fa7e net/hns3: increase VF reset retry maximum
When the device is very busy, VF reset may have to be
retried many times to succeed, leading to the current
max reset fail retry count not enough.

Modify max reset fail retry count to 30 to enhance
the reliability of reset function.

78dbb6f999 net/hns3: fix time delta calculation
Currently, driver uses gettimeofday() API to get the time, and
then calculate the time delta, the delta will be used mainly in
judging timeout process.

But the time which gets from gettimeofday() API isn't monotonically
increasing. The process may fail if the system time is changed.

We use the following scheme to fix it:
1. Add hns3_clock_gettime() API which will get the monotonically
   increasing time.
2. Add hns3_clock_calctime_ms() API which will get the milliseconds of
   the monotonically increasing time.
3. Add hns3_clock_calctime_ms() API which will calc the milliseconds of
   a given time.

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.

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.

5f8845f4ba net/hns3: process MAC interrupt
TNL is the abbreviation of tunnel, which means port
here. MAC TNL interrupt indicates the MAC status
report of the network port, which will be generated
when the MAC status changes.

This patch enables MAC TNL interrupt reporting, and
queries and prints the corresponding MAC status when
the interrupt is received, then clear the MAC interrupt
status. Because this interrupt uses the same interrupt
as RAS, the interrupt log is adjusted.

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.

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.

c4ae39b2cf net/hns3: fix Rx interrupt after reset
Currently, Rx interrupt cannot work normally after reset (such as FLR,
global reset and IMP reset), when running l3fwd-power application based
on hns3 network engine.

The root cause is that the hardware configuration about Rx interrupt
does not recover after reset.

This patch fixes it with the following modification.
1. The internal static function named hns3(vf)_init_ring_with_vector is
   moved from hns3_init_pf to hns3(vf)_init_hardware because
   hns3(vf)_init_hardware is called both in the initialization and the
   RESET_STAGE_DEV_INIT stage of the reset process.
2. The internal static function named hns3(vf)_restore_rx_interrupt is
   added in hns3(vf)_restore_conf, it is used to recover hardware
   configuration about interrupt vectors of rx queues in the
   RESET_STAGE_DEV_INIT stage of the reset process.
3. The internal static function named hns3_dev_all_rx_queue_intr_enable
   and hns3_enable_all_queues are added in hns3(vf)_dev_start(which
   called in the initialization, so after calling the rte_eth_dev_start
   API successfully, the driver is ready to work.
4. The function named hns3_dev_all_rx_queue_intr_enable and
   hns3_enable_all_queues are also added in hns3(vf)_start_service(which
   called in the RESET_STAGE_DEV_INIT stage of the reset process), so
   after start_service, the driver is ready to work.

Note:
1. Because FLR will clear queue's interrupt enable bit hardware
   configuration, so we add calling hns3_dev_all_rx_queue_intr_enable to
   enable interrupt before enabling queues.
2. After finished the initialization, we can enable queues to work by
   calling the internal function named hns3_enable_all_queues.
