For IQD devices with Multi-Write support, we can defer the queue-flush further and transmit multiple IO buffers with a single TX doorbell. The same-target restriction still applies. Signed-off-by:

Madalin Bucur says: ==================== DPAA Ethernet changes v2: remove excess braces Here are some more changes for the DPAA 1.x area. In summary, these changes use pages for the receive buffers and for the scatter-gather table fed to the HW on the Tx path, perform a bit of cleanup in some convoluted parts of the code, add some minor fixes related to DMA (un)mapping sequencing for a not so common scenario, add a device link that removes the interfaces when the QMan portal in use by them is removed. ==================== Signed-off-by: -

Before this change, unbinding the QMan portals did not trigger a corresponding unbinding of the dpaa_eth making use of it; the first QMan portal related operation issued afterwards crashed the kernel. The device link ensures the dpaa_eth dependency upon the qman portal used is honoured at the QMan portal removal. Signed-off-by:

User reports that an application making an (incorrect) call to restart AN on a fixed link DPAA interface triggers an error in the kernel log while the returned EINVAL should be enough. Reported-by:

The dpaa_cleanup_tx_fd() function is called by the frame transmit confirmation callback but also on several error paths. This function is reading the transmit timestamp value. Avoid reading an invalid timestamp value on the error paths. Fixes: 4664856e ("dpaa_eth: add support for hardware timestamping") Signed-off-by:

Change the buffers used for reception from netdev_frags to pages. Signed-off-by:
-
Madalin Bucur authored
Currently the DPAA Ethernet driver is using three buffer pools for each interface, with three different sizes for the buffers provided for the FMan reception path. This patch reduces the number of buffer pools to one per interface. This change is in preparation of another, that will be switching from netdev_frags to page backed buffers for the receive path.

Huazhong Tan says: ==================== net: hns3: add some optimizations and cleanups This series adds some code optimizations and cleanups for the HNS3 ethernet driver. [patch 1/9] dumps some debug information when reset fail. [patch 2/9] dumps some struct netdev_queue information when TX timeout. [patch 3/9] cleanups some magic numbers. [patch 4/9] cleanups some coding style issue. [patch 5/9] fixes a compiler warning. [patch 6/9] optimizes some local variable initialization. [patch 7/9] modifies some comments. [patch 8/9] cleanups some print format warnings. [patch 9/9] cleanups byte order issue. ==================== Signed-off-by: -

Though the hip08 and the IMP(Intelligent Management Processor) have the same byte order right now, it is better to convert __be or __le variable into the CPU's byte order before print. Signed-off-by:

Using '%d' for printing type unsigned int or '%u' for type int would cause static tools to give false warnings, so this patch cleanups this warning by using the suitable format specifier of the type of variable. BTW, modifies the type of some variables and macro to synchronize with their usage. Signed-off-by:

The variable tx_ring is unnecessary to be initialized as it will be set before used, and the variable rst_cnt is better to be initialized when declaration for simplification. Signed-off-by:

In hns3_nic_init_irq(), when '*_int_idx' has more than 9 digits and the length of netdev's name is IFNAMSIZ, the total length of final name will be bigger the HNAE3_INT_NAME_LEN - 1, even though '*_int_idx' will never have such large value, but the compiler gives a format-truncation warning for this case. So this patch just enlarges the length to avoid this warning. Signed-off-by:

To make the code more readable, this patch replaces some magic numbers with macro or sizeof operation. Also uses macro lower_32_bits and upper_32_bits to get bits 0-31 and 32-63 of a number, instead of using type conversion and '>>' operation. No functional change. Signed-off-by:

When there is a TX timeout, we can tell if the driver or stack has stopped the queue by looking at state field, and when has the last packet transmited by looking at trans_start field. So this patch prints these two field in the hns3_get_tx_timeo_queue_info(). Signed-off-by:

Sheetal Tigadoli says: ==================== bnxt_en: Add OP-TEE based bnxt f/w manager This patch series adds support for TEE based BNXT firmware management module and the driver changes to invoke OP-TEE APIs to fastboot firmware and to collect crash dump. Changes from v4: - update Kconfig to reflect dependency on TEE driver ==================== Signed-off-by: -
Vasundhara Volam authored
Driver supports 2 types of core dumps. 1. Live dump - Firmware dump when system is up and running. 2. Crash dump - Dump which is collected during firmware crash that can be retrieved after recovery. Crash dump is currently supported only on specific 58800 chips which can be retrieved using OP-TEE API only, as firmware cannot access this region directly. User needs to set the dump flag using following command before initiating the dump collection: $ ethtool -W|--set-dump eth0 N Where N is "0" for live dump and "1" for crash dump Command to collect the dump after setting the flag: $ ethtool -w eth0 data Filename v3: Modify set_dump to support even when CONFIG_TEE_BNXT_FW=n. Also change log message to netdev_info().

Ido Schimmel says: ==================== mlxsw: Make port split code more generic Jiri says: Currently, we assume some limitations and constant values which are not applicable for Spectrum-3 which has 8 lanes ports (instead of previous 4 lanes). This patch does 2 things: 1) Generalizes the code to not use constants so it can work for 4, 8 and possibly 16 lanes. 2) Enforces some assumptions we had in the code but did not check. ==================== Signed-off-by: -
