Add a lib.sh for net selftests. This file can be used to define commonly used variables and functions. Some commonly used functions can be moved from forwarding/lib.sh to this lib file. e.g. busywait(). Add function setup_ns() for user to create unique namespaces with given prefix name. Reviewed-by:

Tony Nguyen says: ==================== Intel Wired LAN Driver Updates 2023-12-01 (ice) This series contains updates to ice driver only. Konrad provides temperature reporting via hwmon. Arkadiusz adds reporting of Clock Generation Unit (CGU) information via devlink info. Pawel adjusts error messaging for ntuple filters to account for additional possibility for encountering an error. Karol ensures that all timestamps occurring around reset are processed and renames some E822 functions to convey additional usage for E823 devices. Jake provides mechanism to ensure that all timestamps on E822 devices are processed. The following are changes since commit 15bc8121: octeon_ep: set backpressure watermark for RX queues and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE ==================== Link: https://lore.kernel.org/r/20231201180845.219494-1-anthony.l.nguyen@intel.comSigned-off-by:

The E822 hardware for Tx timestamping keeps track of how many outstanding timestamps are still in the PHY memory block. It will not generate a new interrupt to the MAC until all of the timestamps in the region have been read. If somehow all the available data is not read, but the driver has exited its interrupt routine already, the PHY will not generate a new interrupt even if new timestamp data is captured. Because no interrupt is generated, the driver never processes the timestamp data. This state results in a permanent failure for all future Tx timestamps. It is not clear how the driver and hardware could enter this state. However, if it does, there is currently no recovery mechanism. Add a recovery mechanism via the periodic PTP work thread which invokes ice_ptp_periodic_work(). Introduce a new check, ice_ptp_maybe_trigger_tx_interrupt() which checks the PHY timestamp ready bitmask. If any bits are set, trigger a software interrupt by writing to PFINT_OICR. Once triggered, the main timestamp processing thread will read through the PHY data and clear the outstanding timestamp data. Once cleared, new data should trigger interrupts as expected. This should allow recovery from such a state rather than leaving the device in a state where we cannot process Tx timestamps. It is possible that this function checks for timestamp data simultaneously with the interrupt, and it might trigger additional unnecessary interrupts. This will cause a small amount of additional processing. Signed-off-by:

During reset, TX_TSYN interrupt should be processed as it may process timestamps in brief moments before and after reset. Timestamping should be enabled on VSIs at the end of reset procedure. On ice_get_phy_tx_tstamp_ready error, interrupt should not be rearmed because error only happens on resets. Reviewed-by:

Yes, they are in all cases so far, so make use of the already present tcf_act_for_each_action macro to explicitly document this assumption.

Enabled the following EST related interrupts: 1) Constant Gate Control Error (CGCE) 2) Head-of-Line Blocking due to Scheduling (HLBS) 3) Head-of-Line Blocking due to Frame Size (HLBF) 4) Base Time Register error (BTRE) 5) Switch to S/W owned list Complete (SWLC) Also, add EST errors into the ethtool statistic. The commit e49aa315 ("net: stmmac: EST interrupts handling and error reporting") and commit 9f298959 ("net: stmmac: Add EST errors into ethtool statistic") add EST interrupts handling and error reporting support to DWMAC4 core.

Amritha Nambiar says: ==================== Introduce queue and NAPI support in netdev-genl (Was: Introduce NAPI queues support) Add the capability to export the following via netdev-genl interface: - queue information supported by the device - NAPI information supported by the device Introduce support for associating queue and NAPI instance. Extend the netdev_genl generic netlink family for netdev with queue and NAPI data. The queue parameters exposed are: - queue index - queue type - ifindex - NAPI id associated with the queue Additional rx and tx queue parameters can be exposed in follow up patches by stashing them in netdev queue structures. XDP queue type can also be supported in future. The NAPI fields exposed are: - NAPI id - NAPI device ifindex - Interrupt number associated with the NAPI instance - PID for the NAPI thread This series only supports 'get' ability for retrieving certain queue and NAPI attributes. The 'set' ability for configuring queue and associated NAPI instance via netdev-genl will be submitted as a separate patch series.
