Convert mediatek,sgmiiisys bindings to DT schema format. Add maintainer Matthias Brugger, no maintainers were listed in the original documentation. As this node is also referenced by the Ethernet controller and used as SGMII PCS add this fact to the description. Move the file to Documentation/devicetree/bindings/net/pcs/ which seems more appropriate given that the great majority of registers are related to SGMII PCS functionality and only one register represents clock bits.

Introduce DT bindings for the MT7981 SoC to mediatek,net.yaml. Reviewed-by:

Daniel Golle authored
The MediaTek MT7981 SoC comes with two 1G/2.5G SGMII ports, just like MT7986. In addition MT7981 is equipped with a built-in 1000Base-T PHY which can be used with GMAC1. As many MT7981 boards make use of inverting SGMII signal polarity, add new device-tree attribute 'mediatek,pn_swap' to support them. Signed-off-by:

Commit 053fdaa8 ("nfc: mrvl: Move platform_data struct into driver") moves the nfcmrvl.h header file from include/linux/platform_data to the driver's directory, but misses to adjust MAINTAINERS. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. Just remove the file entry in NFC SUBSYSTEM, as the new location of the code is already covered by another pattern in that section.

This seems to be more than just coincidence. Apparently they also need the same workaround for EDPD mode (energy detect power down).

Colin Foster says: ==================== add support for ocelot external ports This is the start of part 3 of what is hopefully a 3-part series to add Ethernet switching support to Ocelot chips. Part 1 of the series (A New Chip) added general support for Ocelot chips that were controlled externally via SPI. https://lore.kernel.org/all/20220815005553.1450359-1-colin.foster@in-advantage.com/ Part 2 of the series (The Ethernet Strikes Back) added DSA Ethernet support for ports 0-3, which are the four copper ports that are internal to the chip. https://lore.kernel.org/all/20230127193559.1001051-1-colin.foster@in-advantage.com/ Part 3 will, at a minimum, add support for ports 4-7, which are configured to use QSGMII to an external phy (Return Of The QSGMII). With any luck, and some guidance, support for SGMII, SFPs, etc. will also be part of this series. V1 was submitted as an RFC - and that was rightly so. I suspected I wasn't doing something right, and that was certainly the case. V2 is much cleaner, so hopefully upgrading it to PATCH status is welcomed. Thanks to Russell and Vladimir for correcting my course from V1. In V1 I included a device tree snippet. I won't repeat that here, but I will include a boot log snippet, in case it is of use: ==================== Signed-off-by:

Ports for Ocelot devices (VSC7511, VSC7512, VSC7513 and VSC7514) support external phys. When external phys are used, additional configuration on each port is required to enable QSGMII mode and set external phy modes. Add a configurable hook into these routines, so the external ports can be used. Signed-off-by:

Add support for the Ocelot SERDES module to support functionality of all non-internal phy ports. Signed-off-by:
-
Colin Foster authored
The phy-ocelot-serdes module has exclusively been used in a syscon setup, from an internal CPU. The addition of external control of ocelot switches via an existing MFD implementation means that syscon is no longer the only interface that phy-ocelot-serdes will see. In the MFD configuration, an IORESOURCE_REG resource will exist for the device. Utilize this resource to be able to function in both syscon and non-syscon configurations. Signed-off-by:

Horatiu Vultur says: ==================== net: lan966x: Improve TX/RX of frames from/to CPU The first patch of this series improves the RX side. As it seems to be an expensive operation to read the RX timestamp for every frame, then read it only if it is required. This will give an improvement of ~70mbit on the RX side. The second patch stops using the packing library. This improves mostly the TX side as this library is used to set diffent bits in the IFH. If this library is replaced with a more simple/shorter implementation, this gives an improvement of more than 100mbit on TX side. All the measurements were done using iperf3. v1->v2: - update lan966x_ifh_set to set the bytes and not each bit individually ==================== Signed-off-by: -
Horatiu Vultur authored
When a frame is injected from CPU, it is required to create an IFH(Inter frame header) which sits in front of the frame that is transmitted. This IFH, contains different fields like destination port, to bypass the analyzer, priotity, etc. Lan966x it is using packing library to set and get the fields of this IFH. But this seems to be an expensive operations. If this is changed with a simpler implementation, the RX will be improved with ~5Mbit while on the TX is a much bigger improvement as it is required to set more fields. Below are the numbers for TX. Before: [ 5] 0.00-10.02 sec 439 MBytes 367 Mbits/sec 0 sender After: [ 5] 0.00-10.00 sec 578 MBytes 485 Mbits/sec 0 sender Signed-off-by:

Whenever a frame was received to the CPU, the HW is timestamping the frame. In the IFH(Inter Frame Header) it is found the nanosecond part of the timestamps the SW is required to read from HW the second part. But reading the second part it seems to be a expensive operations, so so change this such to read the second part only when rx filter is enabled. Doing this change gives the RX a performance boost of ~70mbit. before: [ 5] 0.00-10.01 sec 546 MBytes 457 Mbits/sec 0 sender now: [ 5] 0.00-10.01 sec 652 MBytes 530 Mbits/sec 0 sender Signed-off-by:

Eric Dumazet says: ==================== net: better const qualifier awareness This is a follow-up of d27d367d ("inet: better const qualifier awareness") Adopting container_of_const() to perform (struct sock *)->(protocol sock *) operation is allowing us to propagate const qualifier and thus detect misuses at compile time. Most conversions are trivial, because most protocols did not adopt yet const sk pointers where it could make sense. Only mptcp and tcp patches (end of this series) are requiring small adjustments. ==================== Signed-off-by:

We can change tcp_sk() to propagate its argument const qualifier, thanks to container_of_const(). We have two places where a const sock pointer has to be upgraded to a write one. We have been using const qualifier for lockless listeners to clearly identify points where writes could happen. Add tcp_sk_rw() helper to better document these. tcp_inbound_md5_hash(), __tcp_grow_window(), tcp_reset_check() and tcp_rack_reo_wnd() get an additional const qualififer for their @tp local variables. smc_check_reset_syn_req() also needs a similar change.
