The HNS3 driver supports Wake-on-LAN, which can wake up the server from power off state to power on state by magic packet or magic security packet. ChangeLog: v1->v2: Deleted the debugfs function that overlaps with the ethtool function from suggestion of Andrew Lunn. v2->v3: Return the wol configuration stored in driver, suggested by Alexander H Duyck. v3->v4: Add a helper to go from netdev to the local struct, suggested by Simon Horman and Jakub Kicinski.

2021-08-12net: hns3: add support for triggering reset by ethtoolYufeng Mo1-0/+56
Currently, four reset types are supported for the HNS3 ethernet driver: IMP reset, global reset, function reset, and FLR. Only FLR can now be triggered by the user. To restore the device when an exception occurs, add support for triggering reset by ethtool. Run the "ethtool --reset DEVNAME mgmt | all | dedicated" to trigger the IMP | global | function reset manually. In addition, VF can only trigger function reset.

2021-06-16net: hns3: use bounce buffer when rx page can not be reusedYunsheng Lin1-0/+12
Currently rx page will be reused to receive future packet when the stack releases the previous skb quickly. If the old page can not be reused, a new page will be allocated and mapped, which comsumes a lot of cpu when IOMMU is in the strict mode, especially when the application and irq/NAPI happens to run on the same cpu. So allocate a new frag to memcpy the data to avoid the costly IOMMU unmapping/mapping operation, and add "frag_alloc_err" and "frag_alloc" stats in "ethtool -S ethX" cmd. The throughput improves above 50% when running single thread of iperf using TCP when IOMMU is in strict mode and iperf shares the same cpu with irq/NAPI(rx_copybreak = 2048 and mtu = 1500).

2021-06-16net: hns3: support dma_map_sg() for multi frags skbYunsheng Lin1-0/+3
Using the queue based tx buffer, it is also possible to allocate a sgl buffer, and use skb_to_sgvec() to convert the skb to the sgvec in order to support the dma_map_sg() to decreases the overhead of IOMMU mapping and unmapping. Firstly, it reduces the number of buffers. For example, a tcp skb may have a 66-byte header and 3 fragments of 4328, 32768, and 28064 bytes. With this patch, dma_map_sg() will combine them into two buffers, 66-bytes header and one 65160-bytes fragment by using IOMMU. Secondly, it reduces the number of dma mapping and unmapping. All the original 4 buffers are mapped only once rather than 4 times. The throughput improves above 10% when running single thread of iperf using TCP when IOMMU is in strict mode.

2021-06-16net: hns3: use tx bounce buffer for small packetsYunsheng Lin1-0/+51
when the packet or frag size is small, it causes both security and performance issue. As dma can't map sub-page, this means some extra kernel data is visible to devices. On the other hand, the overhead of dma map and unmap is huge when IOMMU is on. So add a queue based tx shared bounce buffer to memcpy the small packet when the len of the xmitted skb is below tx_copybreak. Add tx_spare_buf_size module param to set the size of tx spare buffer, and add set/get_tunable to set or query the tx_copybreak. The throughtput improves from 30 Gbps to 90+ Gbps when running 16 netperf threads with 32KB UDP message size when IOMMU is in the strict mode(tx_copybreak = 2000 and mtu = 1500).

2021-06-01net: hns3: add support for modify VLAN filter stateJian Shen1-6/+2
Previously, with hardware limitation, the port VLAN filter are effective for both PF and its VFs simultaneously, so a single function is not able to enable/disable separately, and the VLAN filter state is default enabled. Now some device supports each function to bypass port VLAN filter, then each function can switch VLAN filter separately. Add capability flag to check whether the device supports modify VLAN filter state. If flag on, user will be able to modify the VLAN filter state by ethtool -K. Furtherly, the default VLAN filter state is also changed according to whether non-zero VLAN used. Then the device can receive packet with any VLAN tag if only VLAN 0 used. The function hclge_need_enable_vport_vlan_filter() is used to help implement above changes. And the VLAN filter handle for promisc mode can also be simplified by this function.

2021-05-18net: hns3: fix user's coalesce configuration lost issueHuazhong Tan1-41/+23
Currently, when adaptive is on, the user's coalesce configuration may be overwritten by the dynamic one. The reason is that user's configurations are saved in struct hns3_enet_tqp_vector whose value maybe changed by the dynamic algorithm. To fix it, use struct hns3_nic_priv instead of struct hns3_enet_tqp_vector to save and get the user's configuration. BTW, operations of storing and restoring coalesce info in the reset process are unnecessary now, so remove them as well.

2021-03-29net: hns3: add handling for xmit skb with recursive fraglistYunsheng Lin1-0/+2
Currently hns3 driver only handle the xmit skb with one level of fraglist skb, add handling for multi level by calling hns3_tx_bd_num() recursively when calculating bd num and calling hns3_fill_skb_to_desc() recursively when filling tx desc. When the skb has a fraglist level of 24, the skb is simply dropped and stats.max_recursion_level is added to record the error. Move the stat handling from hns3_nic_net_xmit() to hns3_nic_maybe_stop_tx() in order to handle different error stat and add the 'max_recursion_level' and 'hw_limitation' stat. Note that the max recursive level as 24 is chose according to below: commit 48a1df65334b ("skbuff: return -EMSGSIZE in skb_to_sgvec to prevent overflow"). And that we are not able to find a testcase to verify the recursive fraglist case, so Fixes tag is not provided.
