2021-06-16net: hsr: don't check sequence number if tag removal is offloadedGeorge McCollister1-1/+2
Don't check the sequence number when deciding when to update time_in in the node table if tag removal is offloaded since the sequence number is part of the tag. This fixes a problem where the times in the node table wouldn't update when 0 appeared to be before or equal to seq_out when tag removal was offloaded.

2021-06-16net: hns3: use bounce buffer when rx page can not be reusedYunsheng Lin4-0/+41
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: optimize the rx page reuse handling processYunsheng Lin1-22/+22
Current rx page offset only reset to zero when all the below conditions are satisfied: 1. rx page is only owned by driver. 2. rx page is reusable. 3. the page offset that is above to be given to the stack has reached the end of the page. If the page offset is over the hns3_buf_size(), it means the buffer below the offset of the page is usable when the above condition 1 & 2 are satisfied, so page offset can be reset to zero instead of increasing the offset. We may be able to always reuse the first 4K buffer of a 64K page, which means we can limit the hot buffer size as much as possible. The above optimization is a side effect when refacting the rx page reuse handling in order to support the rx copybreak.

2021-06-16net: hns3: support dma_map_sg() for multi frags skbYunsheng Lin3-5/+113
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 Lin4-15/+420
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).

Also move the desc_cb type definition to hns3_enet.h because it is only used in hns3_enet.c, and declare a local variable desc_cb in hns3_clear_desc() to reduce lines of code.
