This patch adds support for offloading timestamping operations not only to the Ocelot switch (as already supported) but to compatible PHYs. When both the PHY and the Ocelot switch support timestamping operations, the PHY implementation is chosen as the timestamp will happen closer to the medium.

Fixed a ton of minor checkpatch errors/warnings and remove version printing at module init/when device is found and use MODULE_VERSION instead. Also modifying the RTL8029 PCI string to include the compatible RTL8029AS nic. The only mayor issue remaining is the missing SPDX tag, but since the exact version of the GPL is not stated anywhere inside the file, its impossible to add such a tag at the moment. But maybe it is possible, since 8390.h states Donald Becker's 8390 drivers are licensed under GPL 2.2 only (= GPL-2.0-only ?). The kernel module containing this patch compiles and runs without problems on a RTL8029AS-based NE2000 clone card with kernel 5.7.0-rc6.

The device has a trap for IPv6 packets that need be routed and have a unicast link-local destination IP (i.e., fe80::/10). This allows mlxsw to ignore link-local routes, as the packets will be trapped to the CPU in any case. However, since link-local routes are not programmed, it is possible for routed packets to hit the default route which might also be programmed to trap packets. This means that packets with a link-local destination IP might be trapped for the wrong reason. To overcome this, allow programming link-local prefix routes (usually one fe80::/64 per-table), so that the packets will be forwarded until reaching the link-local trap.

Bidirectional Forwarding Detection (BFD) provides "low-overhead, short-duration detection of failures in the path between adjacent forwarding engines" (RFC 5880). This is accomplished by exchanging BFD packets between the two forwarding engines. Up until now these packets were trapped via the general local delivery (i.e., IP2ME) trap which also traps a lot of other packets that are not as time-sensitive as BFD packets. Expose dedicated traps for BFD packets so that user space could configure a dedicated policer for them.

As explained in commit e6125230 ("mlxsw: spectrum_trap: Introduce dummy group with thin policer"), the purpose of the "thin" policer is to pass as less packets as possible to the CPU. The identifier of this policer is currently set according to the maximum number of used trap groups, but this is fragile: On Spectrum-1 the maximum number of policers is less than the maximum number of trap groups, which might result in an invalid policer identifier in case the number of used trap groups grows beyond the policer limit. Solve this by dynamically allocating the policer identifier. Signed-off-by: NIdo Schimmel <idosch@mellanox.com> Reviewed-by: NJiri Pirko <jiri@mellanox.com> Signed-off-by: NDavid S.

When a packet enters the device it is classified to a filtering identifier (FID) based on the ingress port and VLAN. The FID miss trap is used to trap packets for which a FID could not be found. In mlxsw this trap should only be triggered when a port is enslaved to an OVS bridge and a matching ACL rule could not be found, so as to trigger learning. These packets are therefore completely unrelated to packets hitting local routes and should be in a different group. Move them.

Packets that are trapped via tc's trap action are currently subject to the same policer as packets hitting local routes. The latter are critical to the correct functioning of the control plane, while the former are mainly used for traffic inspection. Split the ACL trap to a separate group with its own policer. Use a higher priority for these traps than for traps using mirror action (e.g., ARP, IGMP). Otherwise, packets matching both traps will not be forwarded in hardware (because of trap action) and also not forwarded in software because they will be marked with 'offload_fwd_mark'.

The commit da722186 (net: fec: set GPR bit on suspend by DT configuration) set the GPR reigster offset and bit in driver for wake on lan feature. But it introduces two issues here: - one SOC has two instances, they have different bit - different SOCs may have different offset and bit So to support wake-on-lan feature on other i.MX platforms, it should configure the GPR reigster offset and bit from DT. So the patch is to improve the commit da722186 (net: fec: set GPR bit on suspend by DT configuration) to support multiple ethernet instances on i.MX series. v2: * switch back to store the quirks bitmask in driver_data v3: * suggested by Sascha Hauer, use a struct fec_devinfo for abstracting differences between different hardware variants, it can give more freedom to describe the differences.

The current MPLS dissector only parses the first MPLS Label Stack Entry (second LSE can be parsed too, but only to set a key_id). This patch adds the possibility to parse several LSEs by making __skb_flow_dissect_mpls() return FLOW_DISSECT_RET_PROTO_AGAIN as long as the Bottom Of Stack bit hasn't been seen, up to a maximum of FLOW_DIS_MPLS_MAX entries. FLOW_DIS_MPLS_MAX is arbitrarily set to 7. This should be enough for many practical purposes, without wasting too much space. To record the parsed values, flow_dissector_key_mpls is modified to store an array of stack entries, instead of just the values of the first one. A bit field, "used_lses", is also added to keep track of the LSEs that have been set. The objective is to avoid defining a new FLOW_DISSECTOR_KEY_MPLS_XX for each level of the MPLS stack. TC flower is adapted for the new struct flow_dissector_key_mpls layout. Matching on several MPLS Label Stack Entries will be added in the next patch. The NFP and MLX5 drivers are also adapted: nfp_flower_compile_mac() and mlx5's parse_tunnel() now verify that the rule only uses the first LSE and fail if it doesn't. Finally, the behaviour of the FLOW_DISSECTOR_KEY_MPLS_ENTROPY key is slightly modified. Instead of recording the first Entropy Label, it now records the last one. This shouldn't have any consequences since there doesn't seem to have any user of FLOW_DISSECTOR_KEY_MPLS_ENTROPY in the tree. We'd probably better do a hash of all parsed MPLS labels instead (excluding reserved labels) anyway. That'd give better entropy and would probably also simplify the code. But that's not the purpose of this patch, so I'm keeping that as a future possible improvement. Signed-off-by: NGuillaume Nault <gnault@redhat.com> Signed-off-by: NDavid S.
