2024-10-23r8169: avoid unsolicited interruptsHeiner Kallweit
It was reported that after resume from suspend a PCI error is logged and connectivity is broken. Error message is: PCI error (cmd = 0x0407, status_errs = 0x0000) The message seems to be a red herring as none of the error bits is set, and the PCI command register value also is normal. Exception handling for a PCI error includes a chip reset what apparently brakes connectivity here. The interrupt status bit triggering the PCI error handling isn't actually used on PCIe chip versions, so it's not clear why this bit is set by the chip. Fix this by ignoring this bit on PCIe chip versions.

2024-10-22net: atlantic: support reading SFP module infoLorenz Brun
Add support for reading SFP module info and digital diagnostic monitoring data if supported by the module. The only Aquantia controller without an integrated PHY is the AQC100 which belongs to the B0 revision, that's why it's only implemented there. The register information was extracted from a diagnostic tool made publicly available by Dell, but all code was written from scratch by me. This has been tested to work with a variety of both optical and direct attach modules I had lying around and seems to work fine with all of them, including the diagnostics if supported by an optical module. All tests have been done with an AQC100 on an TL-NT521F card on firmware version 3.1.121 (current at the time of this patch).

2024-10-22wifi: ath12k: remove msdu_end structure for WCN7850Lingbo Kong
Currently, when ath12k retrieves values from the structure rx_msdu_end_wcn7850, the information obtained is incorrect. This is because the definition of the rx_msdu_end_wcn7850 structure in ath12k is incorrect. In fact, the rx_msdu_end structure used by WCN7850 is the same as the rx_msdu_end structure of QCN9274. Commit ed823fd113b7 ("wifi: ath12k: add msdu_end structure for WCN7850") introduced this structure. The original issue trying to be fixed with that commit is that the TID information retrieved from the rx_msdu_end structure was incorrect, and it was thought that the structure wasn't correct, so a supposedly correct structure was introduced. However it was subsequently discovered that the TID information is only guaranteed to be valid in the rx_msdu_start structure, so that commit added the logic to retrieve the TID from the rx_msdu_start, but unfortunately kept the rx_msdu_end_wcn7850 structure. To address this issue, revert the code related to the rx_msdu_end_wcn7850 structure, retaining the TID retrieval logic. This patch does not affect QCN9274.

2024-10-22net: netconsole: split send_msg_fragmentedBreno Leitao
Refactor the send_msg_fragmented() function by extracting the logic for sending the message body into a new function called send_fragmented_body(). Now, send_msg_fragmented() handles appending the release and header, and then delegates the task of breaking up the body and sending the fragments to send_fragmented_body(). This is the final flow now: When send_ext_msg_udp() is called to send a message, it will: - call send_msg_no_fragmentation() if no fragmentation is needed or - call send_msg_fragmented() if fragmentation is needed * send_msg_fragmented() appends the header to the buffer, which is be persisted until the function returns * call send_fragmented_body() to iterate and populate the body of the message. It will not touch the header, and it will only replace the body, writing the msgbody and/or userdata. Also add some comment to make the code easier to review.

2024-10-22net: netconsole: introduce variable to track body lengthBreno Leitao
This new variable tracks the total length of the data to be sent, encompassing both the message body (msgbody) and userdata, which is collectively called body. By explicitly defining body_len, the code becomes clearer and easier to reason about, simplifying offset calculations and improving overall readability of the function.

2024-10-22net: netconsole: rename body to msg_bodyBreno Leitao
With the introduction of the userdata concept, the term body has become ambiguous and less intuitive. To improve clarity, body is renamed to msg_body, making it clear that the body is not the only content following the header. In an upcoming patch, the term body_len will also be revised for further clarity. The current packet structure is as follows: release, header, body, [msg_body + userdata] Here, [msg_body + userdata] collectively forms what is currently referred to as "body." This renaming helps to distinguish and better understand each component of the packet.

2024-10-22net: netconsole: split send_ext_msg_udp() functionBreno Leitao
The send_ext_msg_udp() function has become quite large, currently spanning 102 lines. Its complexity, along with extensive pointer and offset manipulation, makes it difficult to read and error-prone. The function has evolved over time, and it’s now due for a refactor. To improve readability and maintainability, isolate the case where no message fragmentation occurs into a separate function, into a new send_msg_no_fragmentation() function. This scenario covers about 95% of the messages. Signed-off-by: Breno Leitao <leitao@debian.org> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2024-10-22net: usb: usbnet: fix name regressionOliver Neukum
The fix for MAC addresses broke detection of the naming convention because it gave network devices no random MAC before bind() was called. This means that the check for the local assignment bit was always negative as the address was zeroed from allocation, instead of from overwriting the MAC with a unique hardware address. The correct check for whether bind() has altered the MAC is done with is_zero_ether_addr Signed-off-by: Oliver Neukum <oneukum@suse.com> Reported-by: Greg Thelen <gthelen@google.com> Diagnosed-by: John Sperbeck <jsperbeck@google.com> Fixes: bab8eb0dd4cb9 ("usbnet: modern method to get random MAC") Link: https://patch.msgid.link/20241017071849.389636-1-oneukum@suse.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2024-10-22net: stmmac: Programming sequence for VLAN packets with split headerAbhishek Chauhan
Currently reset state configuration of split header works fine for non-tagged packets and we see no corruption in payload of any size We need additional programming sequence with reset configuration to handle VLAN tagged packets to avoid corruption in payload for packets of size greater than 256 bytes. Without this change ping application complains about corruption in payload when the size of the VLAN packet exceeds 256 bytes. With this change tagged and non-tagged packets of any size works fine and there is no corruption seen. Current configuration which has the issue for VLAN packet ---------------------------------------------------------- Split happens at the position at Layer 3 header |MAC-DA|MAC-SA|Vlan Tag|Ether type|IP header|IP data|Rest of the payload| 2 bytes ^ | With the fix we are making sure that the split happens now at Layer 2 which is end of ethernet header and start of IP payload Ip traffic split ----------------- Bits which take care of this are SPLM and SPLOFST SPLM = Split mode is set to Layer 2 SPLOFST = These bits indicate the value of offset from the beginning of Length/Type field at which header split should take place when the appropriate SPLM is selected. Reset value is 2bytes. Un-tagged data (without VLAN) |MAC-DA|MAC-SA|Ether type|IP header|IP data|Rest of the payload| 2bytes ^ | Tagged data (with VLAN) |MAC-DA|MAC-SA|VLAN Tag|Ether type|IP header|IP data|Rest of the payload| 2bytes ^ | Non-IP traffic split such AV packet ------------------------------------ Bits which take care of this are SAVE = Split AV Enable SAVO = Split AV Offset, similar to SPLOFST but this is for AVTP packets. |Preamble|MAC-DA|MAC-SA|VLAN tag|Ether type|IEEE 1722 payload|CRC| 2bytes ^ | Signed-off-by: Abhishek Chauhan <quic_abchauha@quicinc.com> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://patch.msgid.link/20241016234313.3992214-1-quic_abchauha@quicinc.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2024-10-21net/mlx5: Only create VEPA flow table when in VEPA modeBenjamin Poirier
Currently, when VFs are created, two flow tables are added for the eswitch: the "fdb" table, which contains rules for each VF and the "vepa_fdb" table. In the default VEB mode, the vepa_fdb table is empty. When switching to VEPA mode, flow steering rules are added to vepa_fdb. Even though the vepa_fdb table is empty in VEB mode, its presence adds some cost to packet processing. In some workloads, this leads to drops which are reported by the rx_discards_phy ethtool counter. In order to improve performance, only create vepa_fdb when in VEPA mode. Tests were done on a ConnectX-6 Lx adapter forwarding 64B packets between both ports using dpdk-testpmd. Numbers are Rx-pps for each port, as reported by testpmd.
