There are some fixes about reset issue and a use-after-free
of self-test.

From: Yonglong Liu
Enable promisc mode of PF, set VF link state to enable, and
run iperf of the VF, then do self test of the PF. The self test
will fail with a low frequency, and may cause a use-after-free
problem.

When asserts VF reset fail, flag HCLGEVF_STATE_CMD_DISABLE

fail. So adds a check for asserting VF reset and returns

Currently the DPRC scan function is used only by the bus driver.
But the same functionality will be needed by the VFIO driver.
To support this, the dprc scan function was exported and a little
bit adjusted to fit both scenarios. Also the scan mutex initialization
is done when

Create and export a cleanup function for DPRC. The function
is used by the DPRC driver, but it will be used by the VFIO
driver as well.

The region size reported by the firmware for mc and software
portals was less than allocated by the hardware. This may be
problematic when mmapping the region in user space because the
region size is less than page size. However the size as reserved
by the hardware is 64K.

The total number of interrupts is only used for some checks
outside the dprc_scan_objects function. Furthermore, in some
situations the check is made twice. Move the bounds check inside
the function for all situations.

When investigating performance issues that involve latency / loss /
reordering it is useful to have the pcap from the sender-side as it
allows to easier infer the state of the sender's congestion-control,
loss-recovery, etc.
Allow the selftests to capture a pcap on both sender and receiver so
that
current hung_task_check_interval_secs and hung_task_timeout_secs
only supports seconds. In some cases,the TASK_UNINTERRUPTIBLE state
takes less than 1 second,may need to hung task trigger panic
get ramdump or print all cpu task.
modify hung_task_check_interval_secs to hung_task_check_interval_msec
