The chipset name (i.e., brand name) used by the driver may cause confusion with the PCI device ID when adding support for new chipsets. | Chipset name | PCI device id | |--------------|----------------| | 7996 | 0x7990, 0x7991 | | 7992 | 0x7992, 0x799a | | 7990 | 0x7993, 0x799b | To prevent confusion, replace the code that directly uses the device ID with macros.

The definition of MT_RX_SEL (for rdd_rx_sel) is mixed with the definition of HWRDD idx. For example, MT_RX_SEL2 is for background HWRDD idx, not an option of rdd_rx_sel. Therefore, add mt7915_get_rdd_idx as a helper function to get the HWRDD idx for each variants. Additionally, remove some parts of the code inherited from the legacy chips. For instance, 1. rdd_state is used for single-band-dual-HWRDD chips (for 80+80), especially the 76xx series. 2. rdd_rx_sel is also used for single-band-dual-HWRDD chips rx_sel = 0 => RDD0 for WF0, RDD1 for WF2 rx_sel = 1 => RDD0 for WF1, RDD1 for WF3 Chip Variants | 5G rdd idx(=bandidx)| Background rdd idx -------------------------------|---------------------|------------------- MT7915A | 0 | 2 MT7915D | 1 | 2 MT7916 2G + 5G (2T2R+1R) | 1 | 2 MT7916 2G + 5G (3T3R) | 1 | N/A MT7981 2G + 5G | 1 | N/A MT7986 2G + 5G (one adie DBDC) | 1 | N/A MT7986 5G (one adie) | 1 (bandidx=MT_BAND1)| N/A MT7986 2G + 5G (dual adie) | 1 | N/A Signed-off-by: StanleyYP Wang <StanleyYP.Wang@mediatek.com> Reviewed-by: Shayne Chen <shayne.chen@mediatek.com> Link: https://patch.msgid.link/20250320015918.3948643-1-StanleyYP.Wang@mediatek.com Signed-off-by: Felix Fietkau <nbd@nbd.name>

Ido Schimmel says: ==================== vxlan: Convert FDB table to rhashtable The VXLAN driver currently stores FDB entries in a hash table with a fixed number of buckets (256), resulting in reduced performance as the number of entries grows. This patchset solves the issue by converting the driver to use rhashtable which maintains a more or less constant performance regardless of the number of entries. Measured transmitted packets per second using a single pktgen thread with varying number of entries when the transmitted packet always hits the default entry (worst case): Number of entries | Improvement ------------------|------------ 1k | +1.12% 4k | +9.22% 16k | +55% 64k | +585% 256k | +2460% The first patches are preparations for the conversion in the last patch. Specifically, the series is structured as follows: Patch #1 adds RCU read-side critical sections in the Tx path when accessing FDB entries. Targeting at net-next as I am not aware of any issues due to this omission despite the code being structured that way for a long time. Without it, traces will be generated when converting FDB lookup to rhashtable_lookup(). Patch #2-#5 simplify the creation of the default FDB entry (all-zeroes). Current code assumes that insertion into the hash table cannot fail, which will no longer be true with rhashtable. Patches #6-#10 add FDB entries to a linked list for entry traversal instead of traversing over them using the fixed size hash table which is removed in the last patch. Patches #11-#12 add wrappers for FDB lookup that make it clear when each should be used along with lockdep annotations. Needed as a preparation for rhashtable_lookup() that must be called from an RCU read-side critical section. Patch #13 treats dst cache initialization errors as non-fatal. See more info in the commit message. The current code happens to work because insertion into the fixed size hash table is slow enough for the per-CPU allocator to be able to create new chunks of per-CPU memory. Patch #14 adds an FDB key structure that includes the MAC address and source VNI. To be used as rhashtable key. Patch #15 does the conversion to rhashtable. ==================== Link: https://patch.msgid.link/20250415121143.345227-1-idosch@nvidia.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

Petr Machata says: ==================== ipmr, ip6mr: Allow MC-routing locally-generated MC packets Multicast routing is today handled in the input path. Locally generated MC packets don't hit the IPMR code. Thus if a VXLAN remote address is multicast, the driver needs to set an OIF during route lookup. In practice that means that MC routing configuration needs to be kept in sync with the VXLAN FDB and MDB. Ideally, the VXLAN packets would be routed by the MC routing code instead. To that end, this patchset adds support to route locally generated multicast packets. However, an installation that uses a VXLAN underlay netdevice for which it also has matching MC routes, would get a different routing with this patch. Previously, the MC packets would be delivered directly to the underlay port, whereas now they would be MC-routed. In order to avoid this change in behavior, introduce an IPCB/IP6CB flag. Unless the flag is set, the new MC-routing code is skipped. All this is keyed to a new VXLAN attribute, IFLA_VXLAN_MC_ROUTE. Only when it is set does any of the above engage. In addition to that, and as is the case today with MC forwarding, IPV4_DEVCONF_MC_FORWARDING must be enabled for the netdevice that acts as a source of MC traffic (i.e. the VXLAN PHYS_DEV), so an MC daemon must be attached to the netdevice. When a VXLAN netdevice with a MC remote is brought up, the physical netdevice joins the indicated MC group. This is important for local delivery of MC packets, so it is still necessary to configure a physical netdevice -- the parameter cannot go away. The netdevice would however typically not be a front panel port, but a dummy. An MC daemon would then sit on top of that netdevice as well as any front panel ports that it needs to service, and have routes set up between the two. A way to configure the VXLAN netdevice to take advantage of the new MC routing would be: # ip link add name d up type dummy # ip link add name vx10 up type vxlan id 1000 dstport 4789 \ local 192.0.2.1 group 225.0.0.1 ttl 16 dev d mrcoute # ip link set dev vx10 master br # plus vlans etc. With the following MC routes: (192.0.2.1, 225.0.0.1) iif=d oil=swp1,swp2 # TX route (*, 225.0.0.1) iif=swp1 oil=d,swp2 # RX route (*, 225.0.0.1) iif=swp2 oil=d,swp1 # RX route The RX path has not changed, with the exception of an extra MC hop. Packets are delivered to the front panel port and MC-forwarded to the VXLAN physical port, here "d". Since the port has joined the multicast group, the packets are locally delivered, and end up being processed by the VXLAN netdevice. This patchset is based on earlier patches from Nikolay Aleksandrov and Roopa Prabhu, though it underwent significant changes. Roopa broadly presented the topic on LPC 2019 [0]. Patchset progression: - Patches #1 to #4 add ip_mr_output() - Patches #5 to #10 add ip6_mr_output() - Patch #11 adds the VXLAN bits to enable MR engagement - Patches #12 to #14 prepare selftest libraries - Patch #15 includes a new test suite [0] https://www.youtube.com/watch?v=xlReECfi-uo ==================== Link: https://patch.msgid.link/cover.1750113335.git.petrm@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
