Lijun Pan says: ==================== ibmvnic: refactor some send/handle functions This patch series rename and factor some send crq request functions. The new naming aligns better with handle* functions such that it make the code easier to read and search by new contributors. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

The only usage of atmtcp_v_dev_ops is to pass its address to atm_dev_register() which takes a pointer to const, and comparing its address to another address, which does not modify it. Make it const to allow the compiler to put it in read-only memory. Signed-off-by:

similarly to what has been done with commit 9d149045 ("geneve: change from tx_error to tx_dropped on missing metadata"), avoid reporting errors to userspace in case the kernel doesn't find any tunnel information for a skb that is going to be transmitted: an increase of tx_dropped is enough. tested with the following script: # for t in ip6gre ip6gretap ip6erspan; do > ip link add dev gre6-test0 type $t external > ip address add dev gre6-test0 2001:db8::1/64 > ip link set dev gre6-test0 up > sleep 30 > ip -s -j link show dev gre6-test0 | jq \ > '.[0].stats64.tx | {"errors": .errors, "dropped": .dropped}' > ip link del dev gre6-test0 > done Reported-by:

Karsten Graul says: ==================== net/smc: introduce SMC-Dv2 support SMC-Dv2 support (see https://www.ibm.com/support/pages/node/6326337) provides multi-subnet support for SMC-D, eliminating the current same-subnet restriction. The new version detects if any of the virtual ISM devices are on the same system and can therefore be used for an SMC-Dv2 connection. Furthermore, SMC-Dv2 eliminates the need for PNET IDs on s390. ==================== Signed-off-by:

SMCD Version 2 allows to propose up to 8 additional ISM devices offered to the peer as candidates for SMCD communication. This patch covers determination of the ISM devices to be proposed. ISM devices without PNETID are preferred, since ISM devices with PNETID are a V1 leftover and will disappear over the time. Signed-off-by:

Tony Nguyen says: ==================== 1GbE Intel Wired LAN Driver Updates 2020-09-28 This series contains updates to igb, igc, and e1000e drivers. Sven Auhagen adds XDP support for igb. Gal Hammer allows for 82576 to display part number string correctly for igb. Sasha adds device IDs for i221 and i226 parts. Exposes LPI counters and removes unused fields in structures for igc. He also adds Meteor Lake support for e1000e. For igc, Andre renames IGC_TSYNCTXCTL_VALID to IGC_TSYNCTXCTL_TXTT_0 to match the datasheet and adds a warning if it's not set when expected. Removes the PTP Tx timestamp check in igc_ptp_tx_work() as it's already checked in the watchdog_task. Cleans up some code by removing invalid error bits, renaming a bit to match datasheet naming, and removing a, now unneeded, macro. Vinicius makes changes for igc PTP: removes calling SYSTIMR to latch timer value, stores PTP time before a reset, and rejects schedules with times in the future. v2: Remove 'inline' from igb_xdp_tx_queue_mapping() and igb_rx_offset() for patch 1 ==================== Signed-off-by: -

When we set the BASET registers of i225 with a base_time in the future, i225 will "hold" all packets until that base_time is reached, causing a lot of TX Hangs. As this behaviour seems contrary to the expectations of the IEEE 802.1Q standard (section 8.6.9, especially 8.6.9.4.5), let's start by rejecting these types of schedules. If this is too limiting, we can for example, setup a timer to configure the BASET registers closer to the start time, only blocking the packets for a "short" while. Signed-off-by:

Vinicius Costa Gomes authored
Many TSN features depend on the internal PTP clock, so the internal PTP jumping when the adapter is reset can cause problems, usually in the form of "TX Hangs" warnings in the driver. The solution is to save the PTP time before a reset and restore it after the reset is done. The value of the PTP time is saved before a reset and we use the difference from CLOCK_MONOTONIC from reset time to now, to correct what's going to be the new PTP time. This is heavily inspired by commit bf4bf09b ("i40e: save PTP time before a device reset"). Signed-off-by:

Completion to commit 900d1e8b ("igc: Add LPI counters") LPI counters exposed by statistics update method. A EEE TX LPI counter reflect the transmitter entries EEE (IEEE 802.3az) into the LPI state. A EEE RX LPI counter reflect the receiver link partner entries into EEE(IEEE 802.3az) LPI state. Signed-off-by:

i225 advanced receive descriptor doesn't have the following extend error bits: CE, SE, SEQ, CXE. In addition to that, the bit TCPE is called L4E in the datasheet. Clean up the code accordingly, and get rid of the macro IGC_RXDEXT_ERR_FRAME_ERR_MASK since it doesn't make much sense anymore. Signed-off-by:

The Tx timestamp timeout is already checked by the watchdog_task which runs periodically. In addition to that, from the ptp_tx work perspective, if __IGC_PTP_TX_IN_PROGRESS flag is set we always want handle the timestamp stored in hardware and update the skb. So remove the timeout check in igc_ptp_tx_work() function. Signed-off-by:

The ptp_tx work is scheduled only if TSICR.TXTS bit is set, therefore TSYNCTXCTL.TXTT_0 bit is expected to be set when we check it igc_ptp_tx_ work(). If it isn't, something is really off and rescheduling the ptp_tx work to check it later doesn't help much. This patch changes the code to WARN_ON_ONCE() if this situation ever happens. Signed-off-by:
