The current per channel DMA interrupt support is based on an edge triggered interrupt that is not maskable. This results in having to call the disable_irq/enable_irq functions in order to prevent interrupts during napi processing. The hardware now has a way to configure the per channel DMA interrupt that will allow for masking the interrupt which prevents calling disable_irq/enable_irq now. This patch makes use of this support. Signed-off-by:

Update the reading of the Tx timestamp to account for a hardware issue on how the fields and interrupt are cleared. The "seconds" portion of the timestamp should be read first, followed by the "nanoseconds" portion. Reading the "nanoseconds" portion should clear the timestamp data and the interrupt. Because of an issue with the hardware this order is reversed and reading the "seconds" portion actually clears the timestamp. The code currently follows this workaround, but to guard against future versions where this is fixed add a field to the version data to indicate if the workaround is required or not. Signed-off-by:

Jiri Benc says: ==================== openvswitch: support for layer 3 encapsulated packets At the core of this patch set is removing the assumption in Open vSwitch datapath that all packets have Ethernet header. The implementation relies on the presence of pop_eth and push_eth actions in datapath flows to facilitate adding and removing Ethernet headers as appropriate. The construction of such flows is left up to user-space. This series is based on work by Simon Horman, Lorand Jakab, Thomas Morin and others. I kept Lorand's and Simon's s-o-b in the patches that are derived from v11 to record their authorship of parts of the code. Changes from v12 to v13: * Addressed Pravin's feedback. * Removed the GRE vport conversion patch; L3 GRE ports should be created by rtnetlink instead. Main changes from v11 to v12: * The patches were restructured and split differently for easier review. * They were rebased and adjusted to the current net-next. Especially MPLS handling is different (and easier) thanks to the recent MPLS GSO rework. * Several bugs were discovered and fixed. The most notable is fragment handling: header adjustment for ARPHRD_NONE devices on tx needs to be done after refragmentation, not before it. This required significant changes in the patchset. Another one is stricter checking of attributes (match on L2 vs. L3 packet) at the kernel level. * Instead of is_layer3 bool, a mac_proto field is used. ==================== Signed-off-by: -

It's not allowed to push Ethernet header in front of another Ethernet header. It's not allowed to pop Ethernet header if there's a vlan tag. This preserves the invariant that L3 packet never has a vlan tag. Based on previous versions by Lorand Jakab and Simon Horman. Signed-off-by:

Extend the ovs flow netlink protocol to support L3 packets. Packets without OVS_KEY_ATTR_ETHERNET attribute specify L3 packets; for those, the OVS_KEY_ATTR_ETHERTYPE attribute is mandatory. Push/pop vlan actions are only supported for Ethernet packets. Based on previous versions by Lorand Jakab and Simon Horman. Signed-off-by:

Support receiving, extracting flow key and sending of L3 packets (packets without an Ethernet header). Note that even after this patch, non-Ethernet interfaces are still not allowed to be added to bridges. Similarly, netlink interface for sending and receiving L3 packets to/from user space is not in place yet. Based on previous versions by Lorand Jakab and Simon Horman. Signed-off-by:

We'll need it to alter packets sent to ARPHRD_NONE interfaces. Change do_output() to use the actual L2 header size of the packet when deciding on the minimum cutlen. The assumption here is that what matters is not the output interface hard_header_len but rather the L2 header of the particular packet. For example, ARPHRD_NONE tunnels that encapsulate Ethernet should get at least the Ethernet header. Signed-off-by:

Use a hole in the structure. We support only Ethernet so far and will add a support for L2-less packets shortly. We could use a bool to indicate whether the Ethernet header is present or not but the approach with the mac_proto field is more generic and occupies the same number of bytes in the struct, while allowing later extensibility. It also makes the code in the next patches more self explaining. It would be nice to use ARPHRD_ constants but those are u16 which would be waste. Thus define our own constants. Another upside of this is that we can overload this new field to also denote whether the flow key is valid. This has the advantage that on refragmentation, we don't have to reparse the packet but can rely on the stored eth.type. This is especially important for the next patches in this series - instead of adding another branch for L2-less packets before calling ovs_fragment, we can just remove all those branches completely.

On tx, use hard_header_len while deciding whether to refragment or drop the packet. That way, all combinations are calculated correctly: * L2 packet going to L2 interface (the L2 header len is subtracted), * L2 packet going to L3 interface (the L2 header is included in the packet lenght), * L3 packet going to L3 interface.

Commit 67f8b1dc ("net/mlx4_en: Refactor the XDP forwarding rings scheme") added a bug in that the prog's reference count is not dropped in the error path when mlx4_en_try_alloc_resources() is failing from mlx4_xdp_set(). We previously took bpf_prog_add(prog, priv->rx_ring_num - 1), that we need to release again. Earlier in the call path, dev_change_xdp_fd() itself holds a reference to the prog as well (hence the '- 1' in the bpf_prog_add()), so a simple atomic_sub() is safe to use here. When an error is propagated, then bpf_prog_put() is called eventually from dev_change_xdp_fd() Fixes: 67f8b1dc ("net/mlx4_en: Refactor the XDP forwarding rings scheme") Signed-off-by:

In current scenario, when the interface is disabled we reset the XGMAC RX/TX functionality. This operation does not affects the PHY layer/SFP and which appears UP to the remote end(this behaviour is unlike GMAC). The result is remote end keeps on sending the packets which gets partly processed by XMAC and dropped. Since these are partly processed these appears as errored packets in the packet counter statistics. This patch fixes this behaviour and adds local-fault and remote-fault functionality which can be used to intimate the remote peer whenever the state of the interface changes. This patch also removes the existing hns_dsaf_xge_core_srst_by_port function which was being used to reset the RX/TX functionality at XGE Core. Reported-by:
