2025-06-19Merge branch 'netdevsim-implement-rx-statistics-using-netdev_pcpu_stat_dstats'Jakub Kicinski
Breno Leitao says: ==================== netdevsim: implement RX statistics using NETDEV_PCPU_STAT_DSTATS The netdevsim driver previously lacked RX statistics support, which prevented its use with the GenerateTraffic() test framework, as this framework verifies traffic flow by checking RX byte counts. This patch migrates netdevsim from its custom statistics collection to the NETDEV_PCPU_STAT_DSTATS framework, as suggested by Jakub. This change not only standardizes the statistics handling but also adds the necessary RX statistics support required by the test framework. v3: https://lore.kernel.org/20250617-netdevsim_stat-v3-0-afe4bdcbf237@debian.org v2: https://lore.kernel.org/20250613-netdevsim_stat-v2-0-98fa38836c48@debian.org v1: https://lore.kernel.org/20250611-netdevsim_stat-v1-0-c11b657d96bf@debian.org ==================== Link: https://patch.msgid.link/20250618-netdevsim_stat-v4-0-19fe0d35e28e@debian.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-06-19netpoll: Extract IPv6 address retrieval functionBreno Leitao
Extract the IPv6 address retrieval logic from netpoll_setup() into a dedicated helper function netpoll_take_ipv6() to improve code organization and readability. The function handles obtaining the local IPv6 address from the network device, including proper address type matching between local and remote addresses (link-local vs global), and includes appropriate error handling when IPv6 is not supported or no suitable address is available.

2025-06-19netdevsim: account dropped packet length in stats on queue freeBreno Leitao
Add a call to dev_dstats_rx_dropped_add() in nsim_queue_free() to account for the number of packets dropped when purging the skb queue. This improves the accuracy of RX drop statistics reported by netdevsim. local_bh_{disable, enable}() protection is used to disable preemption, which is necessary given that dev_dstats_rx_dropped_add() access this_cpu_ptr().

Refactor lan78xx_get_link_ksettings and lan78xx_set_link_ksettings to use the phylink API (phylink_ethtool_ksettings_get and phylink_ethtool_ksettings_set) instead of directly interfacing with the PHY. This change simplifies the code and ensures better integration with the phylink framework for link management. Additionally, the explicit calls to usb_autopm_get_interface() and usb_autopm_put_interface() have been removed. These were originally needed to manage USB power management during register accesses. However, lan78xx_mdiobus_read() and lan78xx_mdiobus_write() already handle USB auto power management internally, ensuring that the interface remains active when necessary. Since there are no other direct register accesses in these functions that require explicit power management handling, the extra calls have become redundant and are no longer needed.

Prior to PHYLINK conversion, this work included reconfiguring the MAC and PHY, effectively performing a 'link reset'. However, after porting the driver to the PHYLINK framework, the logic associated with this event now solely handles the acknowledgment of the PHY interrupt. The MAC and PHY reconfiguration is now managed by PHYLINK's dedicated callbacks. To accurately reflect its current, narrowed functionality, rename EVENT_LINK_RESET to EVENT_PHY_INT_ACK.

Russell King says: ==================== net: stmmac: loongson1: cleanups A couple of patches to cleanup loongson1. First, introducing a match data struct to allow the per-match data to be extended beyond the init function pointer, and then adding a setup method to allow the resource base address to be translated to the MAC index at probe time rather than repeatedly in the setup function. ==================== Link: https://patch.msgid.link/aFKXzlno7HkG-cNh@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-06-19net: stmmac: loongson1: get ls1b resource only onceRussell King (Oracle)
ls1b_dwmac_syscon_init() was getting the stmmac iomem resource to detect which GMAC block is being used. Move this to a separate setup() function that only runs at probe time, so it can sensibly behave with an unrecognised resource adress. Use this to set a MAC index (id) which is then used in place of testing the base address.
