PF needs to assert the VF reset when it receives the request to reset from VF. After receiving request PF ackknowledges the request by replying back MBX_ASSERTING_RESET message to VF. VF then goes to pending state and wait for hardware to complete the reset. This patch contains code to handle the received VF message, inform the VF of assertion and reset the VF using cmdq interface.

Reset Asserting message is forwarded by PF to inform VF about the hardware reset which is about to happen. This might be due to the earlier VF reset request received by the PF or because PF for any reason decides to undergo reset. This message results in VF to go in pending state in which it polls the hardware to complete the reset and then further resets/tears its own stack.

Current mailbox CRQ could consists of both synchronous and async responses from the PF. Synchronous responses are time critical and should be handed over to the waiting tasks/context as quickly as possible otherwise timeout occurs. Above problem gets accentuated if CRQ consists of even single async message. Hence, it is important to have quick handling of synchronous messages and maybe deferred handling of async messages This patch introduces separate ARQ(async receive queues) for the async messages. These messages are processed later with repsect to mailbox task while synchronous messages still gets processed in context to mailbox interrupt. ARQ is important as VF reset introduces some new async messages like MBX_ASSERTING_RESET which adds up to the presssure on the responses for synchronousmessages and they timeout even more quickly.

This introduces the hclge device reset states of "requested" and "pending" and also its handling in context to Reset Service Task. Device gets into requested state because of any VF reset request asserted from upper layers, for example due to watchdog timeout expiration. Requested state would result in eventually forwarding the VF reset request to PF which would actually reset the VF. Device will get into pending state if: 1. VF receives the acknowledgement from PF for the VF reset request it originally sent to PF. 2. Reset Service Task detects that after asserting VF reset for certain times the data-path is not working and device then decides to assert full VF reset(this means also resetting the PCIe interface). 3. PF intimates the VF that it has undergone reset. Pending state would result in VF to poll for hardware reset completion status and then resetting the stack/enet layer, which in turn means reinitializing the ring management/enet layer. Note: we would be adding support of 3. later as a separate patch. This decision should not affect VF reset as its event handling is generic in nature.

HNS3 drivers enet layer, used for the ring management and stack interaction, is common to both VF and PF. PF already supports reset functionality to handle the network stack watchdog timeout trigger but the existing code is not generic enough to be used to support VF reset as well. This patch does following: 1. Makes the existing watchdog timeout handler in enet layer generic i.e. suitable for both VF and PF and 2. Introduces the new reset event handler for the VF code. 3. Changes existing reset event handler of PF code to initialize the reset level Signed-off-by: NSalil Mehta <salil.mehta@huawei.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

In 'auto-neg off' the device have sent AN (auto-negotiation) frames with the forced speed. Thus, fix it using an_disable_admin field in Port type and speed (PTYS) register. This field indicates if speed negotiation frames would be send by the port or not. Add the field and enable/disable it for 'auto-neg on/off', make the port to start/stop sending AN (auto-negotiation) frames. Note that for SwitchX2 the behavior doesn't change (i.e support only AN enabled with forced speed).
