We found the following warning when using W=1 to build kernel: drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:3634:6: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable] int ret, coe = priv->hw->rx_csum; When digging stmmac_get_rx_header_len(), dwmac4_get_rx_header_len() and dwxgmac2_get_rx_header_len() return 0 only, without any error code to report. Therefore, it's better to define get_rx_header_len() as void. Signed-off-by:

David Awogbemila says: ==================== Add GVE Features. Note: Patch 4 in v3 was dropped. Patch 4 (patch 5 in v3): Start/stop timer only when report stats is enabled/disabled. Patch 7 (patch 8 in v3): Use netdev_info, not dev_info, to log device link status. ==================== Acked-by:

This change allows the driver to report the device link speed when the ethtool command: ethtool <nic name> is run. Getting the link speed is done via a new admin queue command: ReportLinkSpeed. Reviewed-by:

This makes the driver better aware of the connectivity status of the device. Based on the device's status register, the driver can call netif_carrier_{on,off}. Reviewed-by:Patricio Noyola <patricion@google.com> Signed-off-by:

This adds per queue NIC stats to ethtool stats and to report-stats. These stats are always exposed to guest whether or not the report-stats flag is turned on. Signed-off-by:

This adds functionality to report driver stats to Hypervisor. (Users may want to turn this feature off as a matter of privacy so a "report-stats" flag is added as an ethtool priv option. It is also disabled by default.) The hypervisor would trigger a stats report in case "too many" packets dropped; the stats would be useful in debugging stuck queues. A "stats_report_trigger_cnt" stat is added to count the number of times the hypervisor attempts to trigger stats report. A timer is also added so that when report-stats is enabled, stat are updated once every 20 seconds. Reviewed-by:

Merge tag 'wireless-drivers-next-2020-09-11' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for v5.10 First set of patches for v5.10. Most noteworthy here is ath11k getting initial support for QCA6390 and IPQ6018 devices. But most of the patches are cleanup: W=1 warning fixes, fallthrough keywords, DMA API changes and tasklet API changes. Major changes: ath10k * support SDIO firmware codedumps * support station specific TID configurations ath11k * add support for IPQ6018 * add support for QCA6390 PCI devices ath9k * add support for NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 to improve PTK0 rekeying wcn36xx * add support for TX ack ==================== Signed-off-by:

Karsten Graul says: ==================== net/smc: updates 2020-09-10 Please apply the following patch series for smc to netdev's net-next tree. This patch series is a mix of various improvements and cleanups. The patches 1 and 10 improve the handling of large parallel workloads. Patch 8 corrects a kernel config default for config CCWGROUP on s390. Patch 9 allows userspace tools to retrieve socket information for more sockets. ==================== Signed-off-by: -

There are 6 types of workers which exist per smc connection. 3 of them are used for listen and handshake processing, another 2 are used for close and abort processing and 1 is the tx worker that moves calls to sleeping functions into a worker. To prevent flooding of the system work queue when many connections are opened or closed at the same time (some pattern uperf implements), move those workers to one of 3 smc-specific work queues. Two work queues are module-global and used for handshake and close workers. The third work queue is defined per link group and used by the tx workers that may sleep waiting for resources of this link group. And in smc_llc_enqueue() queue the llc_event_work work to the system prio work queue because its critical that this work is started fast. Reviewed-by:

arch/s390/net/pnet.c uses ccwgroup function dev_is_ccwgroup() in pnetid_by_dev_port(). For s390 the net/smc code makes use of function pnetid_by_dev_port(). Make sure ccwgroup is built into the kernel, if smc is to be built into the kernel. Signed-off-by:

smc_lgr_cleanup_early() schedules the free worker with delay. DMB unregistering occurs in this delayed worker increasing the risk to reach the SMCD SBA limit without need. Terminate the linkgroup immediately, since termination means early DMB unregistering. For SMCD the global smc_server_lgr_pending lock is given up early. A linkgroup to be given up with smc_lgr_cleanup_early() may already contain more than one connection. Using __smc_lgr_terminate() in smc_lgr_cleanup_early() covers this. And consolidate smc_ism_put_vlan() and smc_put_device() into smc_lgr_free() only. Signed-off-by:

SMC starts a separate tcp_listen worker for every SMC socket in state SMC_LISTEN, and can accept an incoming connection request only, if this worker is really running and waiting in kernel_accept(). But the number of running workers is limited. This patch reworks the listening SMC code and starts a tcp_listen worker after the SYN-ACK handshake on the internal clc-socket only. Suggested-by:

Robert Bałdyga's email does not work (bounces) since 2016 so remove it. Additionally there are no review/ack/tested tags from Krzysztof Opasiak so it looks like the driver is not supported. As a maintainer of Samsung ARM/ARM64 SoC, I can take care about this driver and provide some review. However clearly driver is not in supported mode as I do not work in Samsung anymore.
