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.

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:

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:

Add XDP support to the IGB driver. The implementation follows the IXGBE XDP implementation closely and I used the following patches as basis: 1. commit 92470808 ("ixgbe: add XDP support for pass and drop actions") 2. commit 33fdc82f ("ixgbe: add support for XDP_TX action") 3. commit ed93a398 ("ixgbe: tweak page counting for XDP_REDIRECT") Due to the hardware constraints of the devices using the IGB driver we must share the TX queues with XDP which means locking the TX queue for XDP. I ran tests on an older device to get better numbers. Test machine: Intel(R) Atom(TM) CPU C2338 @ 1.74GHz (2 Cores) 2x Intel I211 Routing Original Driver Network Stack: 382 Kpps Routing XDP Redirect (xdp_fwd_kern): 1.48 Mpps XDP Drop: 1.48 Mpps Using XDP we can achieve line rate forwarding even on an older Intel Atom CPU.

Jakub Kicinski says: ==================== udp_tunnel: convert Intel drivers with shared tables This set converts Intel drivers which have the ability to spawn multiple netdevs, but have only one UDP tunnel port table. Appropriate support is added to the core infra in patch 1, followed by netdevsim support and a selftest. The table sharing works by core attaching the same table structure to all devices sharing the table. This means the reference count has to accommodate potentially large values. Once core is ready i40e and ice are converted. These are complex drivers, but we got a tested-by from Aaron, so we should be good :) Compared to v1 I've made sure the selftest is executable. Other than that patches 8 and 9 are actually from the Mellanox conversion series were kept out to avoid Mellanox vs Intel conflicts. Last patch is new, some docs to let users knows ethtool can now display UDP tunnel info. ==================== Signed-off-by: -

Convert ice to the new infra, use share port tables. Leave a tiny bit more error checking in place than usual, because this driver really does quite a bit of magic. We need to calculate the number of VxLAN and GENEVE entries the firmware has reserved. Thanks to the conversion the driver will no longer sleep in an atomic section. Signed-off-by:
