Define it in nic_common.h, even though the ef100 driver will have a different implementation backing it (actually a WARN_ON_ONCE as it should never get called by ef100.

2020-06-30net: mvneta: fix use of state->speedRussell King1-1/+1
When support for short preambles was added, it incorrectly keyed its decision off state->speed instead of state->interface. state->speed is not guaranteed to be correct for in-band modes, which can lead to short preambles being unexpectedly disabled. Fix this by keying off the interface mode, which is the only way that mvneta can operate at 2.5Gbps.

2020-06-30Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queueDavid S. Miller10-223/+414
Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2020-06-29 This series contains updates to only the igc driver. Sasha added Energy Efficient Ethernet (EEE) support and Latency Tolerance Reporting (LTR) support for the igc driver. Added Low Power Idle (LPI) counters and cleaned up unused TCP segmentation counters. Removed igc_power_down_link() and call igc_power_down_phy_copper_base() directly. Removed unneeded copper media check. Andre cleaned up timestamping by removing un-supported features and duplicate code for i225. Fixed the timestamp check on the proper flag instead of the skb for pending transmit timestamps. Refactored igc_ptp_set_timestamp_mode() to simply the flow. v2: Removed the log message in patch 1 as suggested by David Miller. Note: The locking issue Jakub Kicinski saw in patch 5, currently exists in the current net-next tree, so Andre will resolve the locking issue in a follow-on patch. ==================== Signed-off-by: David S.

2020-06-29igc: Fix Rx timestamp disablingAndre Guedes1-37/+17
When Rx timestamping is enabled, we set the timestamp bit in SRRCTL register for each queue, but we don't clear it when disabling. This patch fixes igc_ptp_disable_rx_timestamp() accordingly. Also, this patch gets rid of igc_ptp_enable_tstamp_rxqueue() and igc_ptp_enable_tstamp_all_rxqueues() and move their logic into igc_ptp_enable_rx_timestamp() to keep the enable and disable helpers symmetric.

2020-06-29igc: Refactor igc_ptp_set_timestamp_mode()Andre Guedes1-50/+53
Current igc_ptp_set_timestamp_mode() logic is a bit tangled since it handles many different hardware configurations in one single place, making it harder to follow. This patch untangles that code by breaking it into helper functions. Quick note about the hw->mac.type check which was removed in this refactoring: this check it not really needed since igc_i225 is the only type supported by the IGC driver.

2020-06-29igc: Remove UDP filter setup in PTP codeAndre Guedes1-50/+1
As implemented in igc_ethtool_get_ts_info(), igc only supports HWTSTAMP_ FILTER_ALL so any HWTSTAMP_FILTER_* option the user may set falls back to HWTSTAMP_FILTER_ALL. HWTSTAMP_FILTER_ALL is implemented via Rx Time Sync Control (TSYNCRXCTL) configuration which timestamps all incoming packets. Configuring a UDP filter, in addition to TSYNCRXCTL, doesn't add much so this patch removes that code. It also takes this opportunity to remove some non-applicable comments.

2020-06-29igc: Check __IGC_PTP_TX_IN_PROGRESS instead of ptp_tx_skbAndre Guedes1-9/+7
The __IGC_PTP_TX_IN_PROGRESS flag indicates we have a pending Tx timestamp. In some places, instead of checking that flag, we check adapter->ptp_tx_skb. This patch fixes those places to use the flag. Quick note about igc_ptp_tx_hwtstamp() change: when that function is called, adapter->ptp_tx_skb is expected to be valid always so we WARN_ON_ONCE() in case it is not. Quick note about igc_ptp_suspend() change: when suspending, we don't really need to check if there is a pending timestamp. We can simply clear it unconditionally.

2020-06-29igc: Remove duplicate code in Tx timestamp handlingAndre Guedes1-19/+15
The functions igc_ptp_tx_hang() and igc_ptp_tx_work() have duplicate code which handles Tx timestamp timeouts. This patch does a trivial refactoring by moving that code to its own function and reusing it.

2020-06-29igc: Clean up Rx timestamping logicAndre Guedes5-58/+5
Differently from I210, I225 doesn't report Rx timestamps via the TS bit Rx descriptor + RXSTMPL/RXSTMPH registers mechanism. Rx timestamps are reported in the packet buffer only, which is implemented by igc_ptp_rx_ pktstamp(). So this patch removes igc_ptp_rx_rgtstamp() and all code related to it, copied from igb driver.
