In orginal codes, the driver only restore VLAN filter entries for PF after reset, the VLAN entries of VF will lose in this case. This patch fixes it by recording VLAN IDs for each function when add VLAN, and restore the VLAN IDs after reset.

Currently, using "ethtool --statistics" can show how many time RX page have been reused, but there is no counter for RX page not being reused. This patch adds non_reuse_pg counter to better debug the performance issue, because it is hard to determine when the RX page is reused or not if there is no such counter. Signed-off-by:

Currently, maybe_stop_tx ops for TSO and non-TSO case share some BD calculation code, so this patch unifies the maybe_stop_tx by removing the maybe_stop_tx ops. skb_is_gso() can be used to differentiate the case between TSO and non-TSO case if there is need to handle special case for TSO case. This patch also add tx_copy field in "ethtool --statistics" to help better debug the performance issue caused by calling skb_copy. Signed-off-by:

hns3_clean_tx_ring calls hns3_nic_reclaim_one_desc to clean buffers and set ring->next_to_clean, then hns3_nic_net_xmit reuses the cleaned buffers. But there are no memory barriers when buffers gets recycled, so the recycled buffers can be corrupted. This patch uses smp_store_release to update ring->next_to_clean and smp_load_acquire to read ring->next_to_clean to properly hand off buffers from hns3_clean_tx_ring to hns3_nic_net_xmit.

When there is only one byte in a frag, the current calculation using "(size + HNS3_MAX_BD_SIZE - 1) >> HNS3_MAX_BD_SIZE_OFFSET" will return zero, because HNS3_MAX_BD_SIZE is 65535 and HNS3_MAX_BD_SIZE_OFFSET is 16. So it will cause tx error when a frag's size is one byte. This patch fixes it by using DIV_ROUND_UP. Fixes: 3fe13ed9 ("net: hns3: avoid mult + div op in critical data path") Signed-off-by:

MAX_SKB_FRAGS in protocol stack is defined as: MAX_SKB_FRAGS is 17 when PAGE_SIZE is 4K. If HW enable GRO, it may merge small packets and the rx buffer may be more than MAX_SKB_FRAGS. So driver will add skb chain when RX buffer num. more than MAX_SKB_FRAGS. Signed-off-by:

The "FE bit" in the description means the last description for a packets. When HW GRO enable, HW write data to ring every packet/buffer, there is greater probability that driver handle with the describtion but HW still not set the "FE bit". When drier handle the packet and HW still not set "FE bit", driver stores skb and bd_num in rx ring, and continue to use the skb and bd_num in next napi. Signed-off-by:

When PF performs a function reset, the hardware will reset both PF and all the VF belong to this PF. Hence, both PF's driver and VF's driver need to perform corresponding reset operations. Before PF driver asserting function reset to hardware, it firstly set up VF's hardware reset status, and inform the VF driver with HNAE3_VF_PF_FUNC_RESET, then VF driver sets this reset type to reset_pending and shechule reset task to stop IO and waits for the hardware reset status to clear. When PF driver has reinitialized the hardware and is ready to process mailbox from VF, PF driver clears VF's hardware reset status for VF to continue its reset process. Also, this patch uses readl_poll_timeout to simplify the hardware reset status waitting. Signed-off-by:

Currently when VF need to reset itself, it will send a cmd to PF, after receiving the VF reset requset, PF sends a cmd to inform VF to enter the reset process and send a cmd to firmware to do the actual reset for the VF, it is possible that firmware has resetted the VF, but VF has not entered the reset process, which may cause IO not stopped problem when firmware is resetting VF. This patch fixes it by adjusting the VF reset process, when VF need to reset itself, it will enter the reset process first, and it will tell the PF to send cmd to firmware to reset itself. Add member reset_pending to struct hclgevf_dev, which indicates that there is reset event need to be processed by the VF's reset task, and the VF's reset task chooses the highest-level one and clears other low-level one when it processes reset_pending. hclge_inform_reset_assert_to_vf function is unused now, but it will be used to support the PF reset with VF working, so declare it in the header file.

While hclge is going to reset, it will notify its client with HNAE3_DOWN_CLIENT, so this client should get into a resetting status from this moment, other operations from the stack need to be blocked as well. And when the reset is finished, the client will be notified with HNAE3_UP_CLIENT, so this is the end of the resetting status. This patch uses HNS3_NIC_STATE_RESETTING flag to implement that, and adds hns3_nic_resetting() to indicate which operation is not allowed. Signed-off-by:

While hardware gets into reset status, the firmware will not respond to driver's command request, which may cause ring not disabled problem during reset process. So this patch uses register instead of command to enable/disable the ring in the enet while doing UP/DOWN operation. Also, HNS3_RING_RX_VM_REG is previously unused, so change it to the correct meaning, and add a wrapper function for readl().

Besides of module_init and module_exit, the process of reset will also uninitialize and initialize the enet client. When reset process fails with enet client uninitialized, the module_exit does not need to uninitialize the enet client, otherwise it may cause double uninitialization problem. So we need the HNS3_NIC_STATE_INITED flag to indicate whether the enet client is initialized. Also HNS3_NIC_STATE_REINITING is previously unused, so change it to HNS3_NIC_STATE_INITED.
