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.

net: hns3: PF support get unicast MAC address space assigned by firmware Currently, there are two ways for PF to set the unicast MAC address space size: specified by config parameters in firmware or set to default value. That's mean if the config parameters in firmware is zero, driver will divide the whole unicast MAC address space equally to 8 PFs. However, in this case, the unicast MAC address space will be wasted a lot when the hardware actually has less then 8 PFs. And in the other hand, if one PF has much more VFs than other PFs, then each function of this PF will has much less address space than other PFs. In order to ameliorate the above two situations, introduce the third way of unicast MAC address space assignment: firmware divides the whole unicast MAC address space equally to functions of all PFs, and calculates the space size of each PF according to its function number. PF queries the space size by the querying device specification command when in initialization process. The third way assignment is lower priority than specified by config parameters, only if the config parameters is zero can be used, and if firmware does not support the third way assignment, then driver still divides the whole unicast MAC address space equally to 8 PFs.

net: hns3: refine the VLAN tag handle for port based VLAN For DEVICE_VERSION_V2, the hardware only supports max two layer VLAN tags, including port based tag inserted by hardware, tag in tx buffer descriptor(get from skb->tci) and tag in packet. For transmit packet: If port based VLAN disabled, and vf driver gets a VLAN tag from skb, the VLAN tag must be filled to the Outer_VLAN_TAG field (tag near to DMAC) of tx buffer descriptor, otherwise it may be inserted after the tag in packet. If port based VLAN enabled, and vf driver gets a VLAN tag from skb, the VLAN tag must be filled to the VLAN_TAG field (tag far to DMAC) of tx buffer descriptor, otherwise it may be conflicted with port based VLAN, and raise a hardware error. For receive packet: The hardware will strip the VLAN tags and fill them in the rx buffer descriptor, no matter port based VLAN enable or not. Because port based VLAN tag is useless for stack, so vf driver needs to discard the port based VLAN tag get from rx buffer descriptor when port based VLAN enabled. So vf must know about the port based VLAN state. For DEVICE_VERSION_V3, the hardware provides some new configuration to improve it. For transmit packet: When enable tag shift mode, hardware will handle the VLAN tag in outer_VLAN_TAG field as VLAN_TAG, so it won't conflict with port based VLAN. And hardware also make sure the tag before the tag in packet. So vf driver doesn't need to specify the tag position according to the port based VLAN state anymore. For receive packet: When enable discard mode, hardware will strip and discard the port based VLAN tag, so vf driver doesn't need to identify it from rx buffer descriptor. So modify the port based VLAN configuration, simplify the process for vf handling the VLAN tag.

To support traffics between functions belong to the same port, we always enable tx promiscuous for broadcast promiscuous, so tx promiscuous for unicast and multicast promiscuous is also enabled. For DEVICE_VERSION_V3, the hardware decouples the above relationship. Tx unicast promiscuous, rx unicast promiscuous, tx multicast promiscuous, rx multicast promiscuous, tx broadcast promiscuous and rx broadcast promiscuous can be enabled separately.

To utilize these new resources, extend the corresponding field or variable to 16bit type, and remove the restriction of NIC client that only use a maximum of 65 interrupt vectors. In addition, the I/O address of the extended interrupt resources are different, so an extra handler is needed. Currently, the total number of interrupts is the sum of RoCE's number and RoCE's offset (RoCE is in front of NIC), since the number of both NIC and RoCE are same. For readability, rewrite the corresponding field of the command, rename the RoCE's offset field as the number of NIC interrupts, then the total number of interrupts is sum of the number of RoCE and NIC, and replace vport->back with hdev in hclge_init_roce_base_info() for simplifying the code.

net: hns3: not allow SSU loopback while execute ethtool -t dev The current loopback mode is to add 0x1F to the SMAC address as the DMAC address and enable the promiscuous mode. However, if the VF address is the same as the DMAC address, the loopback test fails. Loopback can be enabled in three places: SSU, MAC, and serdes. By default, SSU loopback is enabled, so if the SMAC and the DMAC are the same, the packets are looped back in the SSU. If SSU loopback is disabled, packets can reach MAC even if SMAC is the same as DMAC. Therefore, this patch disables the SSU loopback before the loopback test. In this way, the SMAC and DMAC can be the same, and the promiscuous mode does not need to be enabled. And this is not valid in version 0x20. This patch also uses a macro to replace 0x1F.

net: hns3: clear reset interrupt status in hclge_irq_handle() Currently, the reset interrupt is cleared in the reset task, which is too late. Since, when the hardware finish the previous reset, it can begin to do a new global/IMP reset, if this new coming reset type is same as the previous one, the driver will clear them together, then driver can not get that there is another reset, but the hardware still wait for the driver to deal with the second one. So this patch clears PF's reset interrupt status in the hclge_irq_handle(), the hardware waits for handshaking from driver before doing reset, so the driver and hardware deal with reset one by one. BTW, when VF doing global/IMP reset, it reads PF's reset interrupt register to get that whether PF driver's re-initialization is done, since VF's re-initialization should be done after PF's. So we add a new command and a register bit to do that. When VF receive reset interrupt, it sets up this bit, and PF finishes re-initialization send command to clear this bit, then VF do re-initialization.

net: hns3: fix some reset handshake issue Currently, the driver sets handshake status to tell the hardware that the driver have downed the netdev and it can continue with reset process. The driver will clear the handshake status when re-initializing the CMDQ, and does not recover this status when reset fail, which may cause the hardware to wait for the handshake status to be set and not being able to continue with reset process. So this patch delays clearing handshake status just before UP, and recovers this status when reset fail. BTW, this patch adds a new function hclge(vf)_reset_handshake() to deal with the reset handshake issue, and renames HCLGE(VF)_NIC_CMQ_ENABLE to HCLGE(VF)_NIC_SW_RST_RDY which represents this register bit more accurately.

So this patch only allocate RX private buffer if there is enough buffer according to hardware user manual.

These MSIX reported hardware errors are handled using common misc. interrupt handler. Hardware error related registers cannot be cleared in context to the interrupt received as they require *heavy* access to hardware using IMP(Integrated Mangement Processor) commands. Hence, we defer the clearing of such error events till later time. Since, we have defered exact identification of errors we will have to defer the level of receovery/reset which might be required. Hence, a new reset type UNKNOWN reset has been introduced which effectively defers the assertion of the reset till we get hold of kind of errors at later time.
