Stefan Schmidt says: ==================== doc: net: ieee802154: move from plain text to rst The ieee802154 subsystem doc was still in plain text. With the networking book taking shape I thought it was time to do the first step and move it over to rst. This really is only the minimal conversion. I need to take some time to update and extend the docs. The patches are based on net-next, but they only touch the networking book so I would not expect and trouble. From what I have seen they would go through Jonathan's tree after being acked by Dave? If you want this patches against a different tree let me know. ==================== Signed-off-by: -

David noticed the original define was hiding 'err' variable reference. Thats confusing and counterintuitive. Andrew noted the whole macro could be replaced with standard readx_poll kernel macro. This makes code more readable. Signed-off-by:

This is a real stack undercorruption found by kasan build. The issue did no harm normally because it only overflowed 2 bytes after `bitary` array which on most architectures were mapped into `err` local.

Jakub Kicinski says: ==================== nfp: control processor DMA support and RJ45 This series starts with adding support for reporting twisted pair media type in ethtool. Remaining patches add support for using DMA with the control/service processor. Currently we always copy the command data into card's memory. DMA support allows us to have the NSP read the data from host memory by itself. Unfortunately, the FW loading and flashing cannot directly map the buffers for DMA because (a) the firmware ABI returns const buffers, and (b) the buffers may be vmalloc()ed in many mysterious/unmappable way. So just bite the bullet - allocate new host buffer for the command and copy. As Dirk explains, the NSP now supports updating all FWs at once which means the max flashing time grew significantly. He bumps the max wait to avoid timeouts. ==================== Signed-off-by: -

The management firmware now supports being passed a bundle with multiple components to be stored in flash at once. This makes it easier to update all components to a known state with a single user command, however, this also has the potential to increase the time required to perform the update significantly. The management firmware only updates the components out of a bundle which are outdated, however, we need to make sure we can handle the absolute worst case where a CPLD update can take a long time to perform. We set a very conservative total timeout of 900s which already adds a contingency. Signed-off-by:

Newer versions of NSP can access host memory. Simplest access type requires all data to be in one contiguous area. Since we don't have the guarantee on where callers of the NSP ABI will allocate their buffers we allocate a bounce buffer and copy the data in and out. Signed-off-by:

The comphy driver for Armada 3700 by Miquèl Raynal (which is currently in linux-next) does not actually set comphy mode when phy_set_mode_ext is called. The mode is set at next call of phy_power_on. Update the driver to semantics similar to mvpp2: helper mvneta_comphy_init sets comphy mode and powers it on. When mode is to be changed in mvneta_mac_config, first power the comphy off, then call mvneta_comphy_init (which sets the mode to new one). Only do this when new mode is different from old mode. This should also work for Armada 38x, since in that comphy driver methods power_on and power_off are unimplemented. Signed-off-by:

The LS1028A SoC features a PCI Integrated Endpoint Root Complex (IERC) defining several integrated PCI devices, including the ENETC ethernet controller integrated endpoints (IEPs). The IERC implements ECAM (Enhanced Configuration Access Mechanism) to provide access to the PCIe config space of the IEPs. This means the the IEPs (including ENETC) do not support the standard PCIe BARs, instead the Enhanced Allocation (EA) capability structures in the ECAM space are used to fix the base addresses in the system, and the PCI subsystem uses these structures for device enumeration and discovery. The "ranges" entries contain basic information from these EA capabily structures required by the kernel for device enumeration. The current patch also enables the first 2 ENETC PFs (Physiscal Functions) and the associated VFs (Virtual Functions), 2 VFs for each PF. Each of these ENETC PFs has an external ethernet port on the LS1028A SoC. Signed-off-by:

Julian Wiedmann says: ==================== s390/qeth: updates 2019-02-28 please apply one more qeth patch series for net-next. This eliminates some of the quirks in our reset code, and slims down the internal state machine. ==================== Signed-off-by: -
Julian Wiedmann authored
Now that qeth always uses dev_close() to shutdown the interface, we can trust the locking and remove some custom state checks. qeth_l?_stop_card() is no longer called for a card in UP state, so remove the checks there too. This basically makes the UP state obsolete, so rip out the whole thing (except for the sysfs-visible string). Signed-off-by:

It makes no difference whether we 1. manually disarm the HW trap and call the offline code with recovery_mode == 1, or 2. call the offline code with recovery_mode == 0, and let it disarm the HW trap for us. So consolidate the two code paths in the suspend callback. Signed-off-by:
