Subject[PATCH net-next 0/9] Add support of VF Reset to HNS3 VF driver
Date
This patch-set adds the support of VF reset to the existing VF driver.
VF Reset can be triggered due to TX watchdog firing as a result of TX
data-path not working. VF reset could also be a result of some internal
configuration changes if that requires reset, or as a result of the
PF/Core/Global/IMP(Integrated Management Processor) reset happened in
the PF.

Summary of Patches:
* Watchdog timer trigger chnages are present in Patch 1.
* Reset Service Task and related Event handling is present in Patches {2,3}
* Changes to send reset request to PF, reset stack and re-initialization
of the hclge device is present in Patches {4,5,6}
* Changes related to ARQ (Asynchronous Receive Queue) and its event handling
are present in Patches {7,8}
* Changes required in PF to handle the VF Reset request and actually perform
hardware VF reset is there in Patch 9.


NOTE: This patch depends upon "[PATCH net-next 00/11] fix some bugs for HNS3 driver"
