2020-09-28Merge branch '1GbE' of https://github.com/anguy11/next-queueDavid S. Miller
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: David S.

2020-09-28igc: Reject schedules with a base_time in the futureVinicius Costa Gomes
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.

2020-09-28igc: Save PTP time before a resetVinicius Costa Gomes
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 bf4bf09bdd91 ("i40e: save PTP time before a device reset").

Add XDP support to the IGB driver.

I ran tests on an older device to get better numbers.

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.
