Set ethtool_ops->supported_coalesce_params to let the core reject unsupported coalescing parameters. This driver was rejecting almost all unsupported parameters already, it was only missing a check for tx_max_coalesced_frames_irq. As a side effect of these changes the error code for unsupported params changes from ENOTSUPP to EOPNOTSUPP. Signed-off-by:

Converting fallthrough comments to fallthrough; creates warnings in this code when compiled with gcc. This code is overly complicated and reads rather better with a little refactoring and no fallthrough uses at all. Remove the fallthrough comments and simplify the written source code while reducing the object code size.

The definitions for the "qcom,smem-states" and "qcom,smem-state-names" properties need to list their "$ref" under an "allOf" keyword. In addition, fix two problems in the example at the end: - Use #include for header files that define needed symbolic values - Terminate the line that includes the "ipa-shared" register space name with a comma rather than a semicolon Finally, update some white space in the example for better alignment.

In their .attach callback, mq[prio] only add the qdiscs of the currently active TX queues to the device's qdisc hash list. If a user later increases the number of active TX queues, their qdiscs are not visible via eg. 'tc qdisc show'. Add a hook to netif_set_real_num_tx_queues() that walks all active TX queues and adds those which are missing to the hash list.

The NCM specification defines two formats of transfer blocks: with 16-bit fields (NTB-16) and with 32-bit fields (NTB-32). Currently only NTB-16 is implemented. This patch adds the support of NTB-32. The motivation behind this is that some devices such as E5785 or E5885 from the current generation of Huawei LTE routers do not support NTB-16. The previous generations of Huawei devices are also use NTB-32 by default. Also this patch enables NTB-32 by default for Huawei devices. During the 2019 ValdikSS made five attempts to contact Huawei to add the NTB-16 support to their router firmware, but they were unsuccessful. Signed-off-by:

Jakub Kicinski says: ==================== ethtool: consolidate irq coalescing - part 3 Convert more drivers following the groundwork laid in a recent patch set [1] and continued in [2]. The aim of the effort is to consolidate irq coalescing parameter validation in the core. This set converts 15 drivers in drivers/net/ethernet. 3 more conversion sets to come. None of the drivers here checked all unsupported parameters.
