This patch introduces the module_sdio_driver macro which is a convenience macro for SDIO driver modules similar to module_usb_driver. It is intended to be used by drivers which init/exit section does nothing but register/ unregister the SDIO driver. By using this macro it is possible to eliminate a few lines of boilerplate code per SDIO driver.

Many functions obtain a 'struct qca_serdev' only to read the btsoc_type field. Add a helper function that encapsulates this. This also fixes crashes observed on platforms with ROME controllers that are instantiated through ldisc and not as serdev clients. The crashes are caused by NULL pointer dereferentiations, which stem from the driver's assumption that a QCA HCI device is always associated with a serdev device.

This adds the support of enabling MT7663S and MT7668S SDIO-based Bluetooth function. There are quite many differences between MT766[3,8]S and standard Bluetooth SDIO devices such as Type-A and Type-B devices. For example, MT766[3,8]S have its own SDIO registers layout, definition, SDIO packet format, and the specific flow should be programmed on them to complete the device initialization and low power control and so on. Currently, there are many independent programming sequences from the transport which are exactly the same as the ones in btusb.c about MediaTek support [1] and btmtkuart.c. We can try to split the transport independent Bluetooth setups on the advance, place them into the common files and allow varous transport drivers to reuse them in the future.

Ido Schimmel says: ==================== mlxsw: Shared buffer improvements This patchset includes two improvements with regards to shared buffer configuration in mlxsw. The first part of this patchset forbids the user from performing illegal shared buffer configuration that can result in unnecessary packet loss. In order to better communicate these configuration failures to the user, extack is propagated from devlink towards drivers. This is done in patches #1-#8. The second part of the patchset deals with the shared buffer configuration of the CPU port. When a packet is trapped by the device, it is sent across the PCI bus to the attached host CPU. From the device's perspective, it is as if the packet is transmitted through the CPU port. While testing traffic directed at the CPU it became apparent that for certain packet sizes and certain burst sizes, the current shared buffer configuration of the CPU port is inadequate and results in packet drops. The configuration is adjusted by patches #9-#14 that create two new pools - ingress & egress - which are dedicated for CPU traffic. ==================== Acked-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.

The CPU port is used to transmit traffic that is trapped to the host CPU. It is therefore irrelevant to define ingress quota for it. Add a 'skip_ingress' argument to the function tasked with configuring per-port quotas, so that ingress quotas could be skipped in case the passed local port is the CPU port.

The function is used to set the per-port shared buffer quotas. Currently, these quotas are only set for front panel ports, but a subsequent patch will configure these quotas for the CPU port as well. The configuration required for the CPU port is a bit different than that of the front panel ports, so split the business logic into a separate function which will be called with different parameters for the CPU port.

Use the new ingress pool that was added in the previous patch for control packets (e.g., STP, LACP) that are trapped to the CPU. The previous management pool is no longer necessary and therefore its size is set to 0. The maximum quota for traffic towards the CPU is increased to 50% of the free space in the new ingress pool and therefore the reserved space is reduced by half, to 10KB - in both the shared and headroom buffer. This allows for more efficient utilization of the shared buffer as reserved space cannot be used for other purposes.

Packets that are trapped to the CPU are transmitted through the CPU port to the attached host. The CPU port is therefore like any other port and needs to have shared buffer configuration. The maximum quotas configured for the CPU are provided using dynamic threshold and cannot be changed by the user. In order to make sure that these thresholds are always valid, the configuration of the threshold type of these pools is forbidden.

The code currently assumes that ingress pools have lower indices than egress pools. This makes it impossible to add more ingress pools without breaking user configuration that relies on a certain pool index to correspond to an egress pool.

Paul Gortmaker says: ==================== clean up needless use of module infrastructure People can embed modular includes and modular exit functions into code that never use any of it, and they won't get any errors or warnings. Using modular infrastructure in non-modules might seem harmless, but some of the downfalls this leads to are: (1) it is easy to accidentally write unused module_exit removal code (2) it can be misleading when reading the source, thinking a driver can be modular when the Makefile and/or Kconfig prohibit it (3) an unused include of the module.h header file will in turn include nearly everything else; adding a lot to CPP overhead. (4) it gets copied/replicated into other drivers and spreads quickly. As a data point for #3 above, an empty C file that just includes the module.h header generates over 750kB of CPP output. Repeating the same experiment with init.h and the result is less than 12kB; with export.h it is only about 1/2kB; with both it still is less than 12kB. One driver in this series gets the module.h ---> init.h+export.h conversion. Worse, are headers in include/linux that in turn include <linux/module.h> as they can impact a whole fleet of drivers, or a whole subsystem, so special care should be used in order to avoid that. Such headers should only include what they need to be stand-alone; they should not be trying to anticipate the various header needs of their possible end users. In this series, four include/linux headers have module.h removed from them because they don't strictly need it. Then three chunks of net related code have modular infrastructure that isn't used, removed. There are no runtime changes, so the biggest risk is a genuine consumer of module.h content relying on implicitly getting it from one of the include/linux instances removed here - thus resulting in a build fail. With that in mind, allmodconfig build testing was done on x86-64, arm64, x86-32, arm. powerpc, and mips on linux-next (and hence net-next). ==================== Signed-off-by: David S.

The Kconfig currently controlling compilation of this code is: net/strparser/Kconfig:config STREAM_PARSER net/strparser/Kconfig: def_bool n ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. For clarity, we change the fcn name mod_init to dev_init at the same time. We replace module.h with init.h and export.h ; the latter since this file exports some syms. Cc: "David S.

Ideally, header files under include/linux shouldn't be adding includes of other headers, in anticipation of their consumers, but just the headers needed for the header itself to pass parsing with CPP. The module.h is particularly bad in this sense, as it itself does include a whole bunch of other headers, due to the complexity of module support. Since tc_ife.h is not going into a module struct looking for specific fields, we can just let it know that module is a struct, just like about 60 other include/linux headers already do.

The module.h is particularly bad in this sense, as it itself does include a whole bunch of other headers, due to the complexity of module support. There doesn't appear to be anything in psample.h that is module related, and build coverage doesn't appear to show any other files/drivers relying implicitly on getting it from here. So it appears we are simply free to just remove it in this case. Cc: Yotam Gigi <yotam.gi@gmail.com> Cc: "David S.

The header contains rtnh_ macros so rename the file accordingly. Allows a later patch to use the nexthop.h name for the new nexthop code. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This patch makes trivial whitespace fix to the function tcp_v4_check at include/net/tcp.h file. It has stylistic issue, which is "space required after that ','" and it can be confirmed with ./scripts/checkpatch.pl tool. ERROR: space required after that ',' (ctx:VxV) #29: FILE: include/net/tcp.h:1317: + return csum_tcpudp_magic(saddr,daddr,len,IPPROTO_TCP,base); ^ Signed-off-by: Daniel T.
