Currently, the hclge_reset_prepare_general function uses the goto
statement to jump upwards, which increases code complexity and makes
the program structure difficult to understand. In addition, if
reset_pending is set, retry_cnt cannot be increased. This may result
in a failure to exit the retry or increase the number of retries.

Use the while statement instead to make the program easier to understand
and solve the problem that the goto statement cannot be exited.

When PF is set to multi-TCs and configured mapping relationship between
priorities and TCs, the hardware will active these settings for this PF
and its VFs.

In this case when VF just uses one TC and its rx packets contain priority,
and if the priority is not mapped to TC0, as other TCs of VF is not valid,
hardware always put this kind of packets to the queue 0. It cause this kind
of packets of VF can not be used RSS function.

To fix this problem, set tc mode of all unused TCs of VF to the setting of
TC0, then rx packet with priority which map to unused TC will be direct to
TC0.

CVE: NA

----------------------------------------------------------------------

When the driver processes rx packets, the head pointer is updated only
after the number of received packets reaches 16. However, hardware
relies on the head pointer to calculate the number of FBDs. As a result,
the hardware calculates the FBD incorrectly. Therefore, the driver
proactively updates the head pointer in each common poll to ensure that
the number of FBDs calculated by the hardware is correct.

----------------------------------------------------------------------

Currently, driver will send command to firmware to query pfc packet number
when user uses dcb tool to get pfc parameters. However, the periodic
service task will also periodically query and record MAC statistics,
including pfc packet number.

As the hardware registers of statistics is cleared after reading, it will
cause pfc packet number of MAC statistics are not correct after using dcb
tool to get pfc parameters.

To fix this problem, when user uses dcb tool to get pfc parameters, driver
updates MAC statistics firstly and then get pfc packet number from MAC
statistics.

Currently, NIC init ROCE interrupt vector with MSIX interrupt. But ROCE use
pci_irq_vector() to get interrupt vector, which adds the relative interrupt
vector again and gets wrong interrupt vector.

So fixes it by assign relative interrupt vector to ROCE instead of MSIX
interrupt vector and delete the unused struct member base_msi_vector

----------------------------------------------------------------------

Currently, when driver is failed to add a new multicast mac address to
hardware due to the multicast mac table is full, it will directly return.
In this case, if the multicast mac list has some reuse addresses after the
new address, those reuse addresses will never be added to hardware.

To fix this problem, if function hclge_add_mc_addr_common() returns
-ENOSPC, hclge_sync_vport_mac_list() should judge whether continue or
stop to add next address.

As function hclge_sync_vport_mac_list() needs parameter mac_type to know
whether is uc or mc, refine this function to add parameter mac_type and
remove parameter sync. So does function hclge_unsync_vport_mac_list().

----------------------------------------------------------------------

The mac statistics add pause/pfc durations in device version V3, we can
get total active cycle of pause/pfc from these durations.

As driver gets register number from firmware to calculate desc number to
query mac statistics, it needs to set mac statistics extended enable bit
in firmware command 0x701A to tell firmware that driver supports extended
mac statistics, otherwise firmware only returns register number of
version V1.

As pause/pfc durations are not supported by hardware of old version, they
should not been shown in command "ethtool -S ethX" in this case, so add
checking max register number of each mac statistic in their version.
If the max register number of one mac statistic is greater than register
number got from firmware, it means hardware does not support this mac
statistic, so ignore this statistic when get string and data of mac
statistic.

CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0bd7e894dffa

----------------------------------------------------------------------

After querying mac statistics from firmware, driver copies data from
descriptors to struct mac_stats of hdev, and the number of copied data
is just according to the register number queried from firmware. There is
a problem that if the register number queried from firmware is larger
than data number of struct mac_stats, it will cause a copy overflow.

So if the firmware adds more mac statistics in later version, it is not
compatible with driver of old version.

To fix this problem, the number of copied data needs to be used the
minimum value between the register number queried from firmware and
data number of struct mac_stats.

The first descriptor has three data and there is one reserved, to
optimize the copy process, add this reserverd data to struct mac_stats.
