amd-xgbe: Add support for new port mode

2020-09-02T19:47:50+00:00

Add support for a new port mode that is a backplane connection without support for auto negotiation. Signed-off-by: Shyam Sundar S K Signed-off-by: David S. Miller

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

xgbe: convert to new udp_tunnel_nic infra

2020-07-15T00:04:27+00:00

Make use of the new udp_tunnel_nic infra. Don't clear the features when VxLAN port is not present to make all drivers behave the same. Driver will now (until we address the problem in the core) leave the RX UDP tunnel feature always on, since this is what most drivers do. Remove the list of VxLAN ports, just program the one core told us to. The driver seem to want to clear the VxLAN ports on close but it doesn't seem to flush the port list properly so it'd get wrong use counts after close/open. Again since it calls its own open handler we need the reset notification hack. v2: - fix kbuild warning Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

xgbe: switch to more generic VxLAN detection

2020-07-15T00:04:27+00:00

Instead of looping though the list of ports just check if the geometry of the packet is correct for VxLAN. HW most likely doesn't care about the exact port, anyway, since only first port is actually offloaded, and this way we won't have to maintain the port list at all.

pcnet32: switch from 'pci_' to 'dma_' API

2020-07-14T00:54:31+00:00

The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GPF_ with a correct flag. It has been compile tested. When memory is allocated in 'pcnet32_realloc_tx_ring()' and 'pcnet32_realloc_rx_ring()', GFP_ATOMIC must be used because a spin_lock is hold. The call chain is: pcnet32_set_ringparam ** spin_lock_irqsave(&lp->lock, flags); --> pcnet32_realloc_tx_ring --> pcnet32_realloc_rx_ring ** spin_unlock_irqrestore(&lp->lock, flags); When memory is in 'pcnet32_probe1()' and 'pcnet32_alloc_ring()', GFP_KERNEL can be used. While at it, update a few comments and pr_err messages to be more in line with the new function names. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET Signed-off-by: David S.
