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.
