2024-03-12vxlan: Remove generic .ndo_get_stats64Breno Leitao1-2/+0
Commit 3e2f544dd8a33 ("net: get stats64 if device if driver is configured") moved the callback to dev_get_tstats64() to net core, so, unless the driver is doing some custom stats collection, it does not need to set .ndo_get_stats64. Since this driver is now relying in NETDEV_PCPU_STAT_TSTATS, then, it doesn't need to set the dev_get_tstats64() generic .ndo_get_stats64 function pointer.

2024-03-12vxlan: Do not alloc tstats manuallyBreno Leitao1-11/+2
With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and convert veth & vrf"), stats allocation could be done on net core instead of in this driver. With this new approach, the driver doesn't have to bother with error handling (allocation failure checking, making sure free happens in the right spot, etc). This is core responsibility now. Remove the allocation in the vxlan driver and leverage the network core allocation instead.

When creating a helper to allocate and align an skb one location where the skb data size was updated was missed. This can lead to a warning being printed when the memory is being unmapped as it now always unmap the maximum frame size, instead of the size after it have been aligned.

2024-03-12net: wan: framer/pef2256: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

For resilient groups, we can reuse the same counter for all the buckets that share the same nexthop. Keep a reference count per counter, and keep all these counters in a per-next hop group xarray, which serves as a NHID->counter cache. If a counter is already present for a given NHID, just take a reference and use the same counter.

2024-03-12mlxsw: spectrum_router: Support nexthop group hardware statisticsPetr Machata1-6/+142
When hw_stats is set on a group, install nexthop counters on members of a group. Counter allocation request is moved from nexthop object initialization to the update code. The previous placement made sense: when the counters are enabled by dpipe, the counters are installed to all existing nexthops and all nexthops created from then on get them. For the finer-grained nexthop group statistics, this is unsuitable. The existing placement was kept for the IPv4 and IPv6 nexthops. Resilient group replacement emits a pre_replace notification, and then any bucket_replace notifications if there were any replacements at all. If the group is balanced and the nexthop composition of the replaced group didn't change, there will be no such notifiers. Therefore hook to the pre_replace notifier and mark all buckets for update, to un/install the counters. When reporting deltas for resilient groups, use the nexthop ID that we stored in a previous patch to look up to which nexthop a bucket contributes.

The core interfaces for collecting per-NH statistics are built around nexthops even for resilient groups. Because mlxsw models each bucket as a nexthop, the core next hop that a given bucket contributes to needs to be looked up.

2024-03-11net: dsa: mt7530: disable LEDs before resetJustin Swartz1-0/+6
Disable LEDs just before resetting the MT7530 to avoid situations where the ESW_P4_LED_0 and ESW_P3_LED_0 pin states may cause an unintended external crystal frequency to be selected. The HT_XTAL_FSEL (External Crystal Frequency Selection) field of HWTRAP (the Hardware Trap register) stores a 2-bit value that represents the state of the ESW_P4_LED_0 and ESW_P4_LED_0 pins (seemingly) sampled just after the MT7530 has been reset, as: ESW_P4_LED_0 ESW_P3_LED_0 Frequency ----------------------------------------- 0 1 20MHz 1 0 40MHz 1 1 25MHz The value of HT_XTAL_FSEL is bootstrapped by pulling ESW_P4_LED_0 and ESW_P3_LED_0 up or down accordingly, but: if a 40MHz crystal has been selected and the ESW_P3_LED_0 pin is high during reset, or a 20MHz crystal has been selected and the ESW_P4_LED_0 pin is high during reset, then the value of HT_XTAL_FSEL will indicate that a 25MHz crystal is present. By default, the state of the LED pins is PHY controlled to reflect the link state. To illustrate, if a board has: 5 ports with active low LED control, and HT_XTAL_FSEL bootstrapped for 40MHz. When the MT7530 is powered up without any external connection, only the LED associated with Port 3 is illuminated as ESW_P3_LED_0 is low. In this state, directly after mt7530_setup()'s reset is performed, the HWTRAP register (0x7800) reflects the intended HT_XTAL_FSEL (HWTRAP bits 10:9) of 40MHz: mt7530-mdio mdio-bus:1f: mt7530_read: 00007800 == 00007dcf >>> bin(0x7dcf >> 9 & 0b11) '0b10' But if a cable is connected to Port 3 and the link is active before mt7530_setup()'s reset takes place, then HT_XTAL_FSEL seems to be set for 25MHz: mt7530-mdio mdio-bus:1f: mt7530_read: 00007800 == 00007fcf >>> bin(0x7fcf >> 9 & 0b11) '0b11' Once HT_XTAL_FSEL reflects 25MHz, none of the ports are functional until the MT7621 (or MT7530 itself) is reset. By disabling the LED pins just before reset, the chance of an unintended HT_XTAL_FSEL value is reduced.

Passing traffic through different devices belonging to different NUMA sockets saves cross-numa traffic and allows apps running on the same netdev from different numas to still feel a sense of proximity to the device and achieve improved performance. We achieve this by grouping PFs together, and creating the netdev only once all group members are probed. Symmetrically, we destroy the netdev once any of the PFs is removed. The channels are distributed between all devices, a proper configuration would utilize the correct close numa when working on a certain app/cpu. We pick one device to be a primary (leader), and it fills a special role. The other devices (secondaries) are disconnected from the network in the chip level (set to silent mode). All RX/TX traffic is steered through the primary to/from the secondaries.
