2023-03-20net: ethernet: mtk_eth_soc: add support for MT7981 SoCDaniel Golle
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.

2023-03-20MAINTAINERS: remove file entry in NFC SUBSYSTEM after platform_data movementLukas Bulwahn
Commit 053fdaa841bd ("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.

Currently one counter is shared between all IPsec Tx offloaded rules to count the total amount of packets/bytes that was IPsec Tx offloaded, replace this scheme by adding a new flow table (ft) with one rule that counts all flows that passes through this table (like Rx status ft), this ft is pointed by all IPsec Tx offloaded rules.

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.

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: David S. Miller <davem@davemloft.net>
2023-03-19net: lan966x: Stop using packing libraryHoratiu Vultur
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: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S.

2023-03-19net: lan966x: Don't read RX timestamp if not neededHoratiu Vultur
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: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S.

2023-03-17net/mlx5e: TC, Add support for VxLAN GBP encap/decap flows offloadGavin Li
Add HW offloading support for TC flows with VxLAN GBP encap/decap. Example of encap rule: tc filter add dev eth0 protocol ip ingress flower \ action tunnel_key set id 42 vxlan_opts 512 \ action mirred egress redirect dev vxlan1 Example of decap rule: tc filter add dev vxlan1 protocol ip ingress flower \ enc_key_id 42 enc_dst_port 4789 vxlan_opts 1024 \ action tunnel_key unset action mirred egress redirect dev eth0 Signed-off-by: Gavin Li <gavinl@nvidia.com> Reviewed-by: Gavi Teitz <gavi@nvidia.com> Reviewed-by: Roi Dayan <roid@nvidia.com> Reviewed-by: Maor Dickman <maord@nvidia.com> Acked-by: Saeed Mahameed <saeedm@nvidia.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-03-17net/mlx5e: Add helper for encap_info_equal for tunnels with optionsGavin Li
For tunnels with options, eg, geneve and vxlan with gbp, they share the same way to compare the headers and options. Extract the code as a common function for them.
