These functions are implemented in mcdi_port.c, which will not be linked into the EF100 driver; thus their prototypes should not be visible in common header files. Signed-off-by:

state->link has never been valid in mac_config() implementations - while it may be correct in some calls, it is not true that it can be relied upon. Fix bcm_sf2 to use the correct method of handling forced link status. Reviewed-by:

Convert the B53 driver to use the finalised link parameters in mac_link_up() rather than the parameters in mac_config(). This is just a matter of moving the call to b53_force_port_config(). Reviewed-by:

Replace the b53_force_port_config() pause argument, which is based on phylink's MLO_PAUSE_* definitions, to use a pair of booleans. This will allow us to move b53_force_port_config() from b53_phylink_mac_config() to b53_phylink_mac_link_up(). Reviewed-by:

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:

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.

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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.

Ido Schimmel says: ==================== Add ethtool extended link state Amit says: Currently, device drivers can only indicate to user space if the network link is up or down, without additional information. This patch set provides an infrastructure that allows these drivers to expose more information to user space about the link state. The information can save users' time when trying to understand why a link is not operationally up, for example. The above is achieved by extending the existing ethtool LINKSTATE_GET command with attributes that carry the extended state. For example, no link due to missing cable: $ ethtool ethX ... Link detected: no (No cable) Beside the general extended state, drivers can pass additional information about the link state using the sub-state field. For example: $ ethtool ethX ... Link detected: no (Autoneg, No partner detected) In the future the infrastructure can be extended - for example - to allow PHY drivers to report whether a downshift to a lower speed occurred. Something like: $ ethtool ethX ... Link detected: yes (downshifted) Patch set overview: Patches #1-#3 move mlxsw ethtool code to a separate file Patches #4-#5 add the ethtool infrastructure for extended link state Patches #6-#7 add support of extended link state in the mlxsw driver Patches #8-#10 add test cases Changes since v1: * In documentation, show ETHTOOL_LINK_EXT_STATE_* and ETHTOOL_LINK_EXT_SUBSTATE_* constants instead of user-space strings * Add `_CI_` to cable_issue substates to be consistent with other substates * Keep the commit messages within 75 columns * Use u8 variable for __link_ext_substate * Document the meaning of -ENODATA in get_link_ext_state() callback description * Do not zero data->link_ext_state_provided after getting an error * Use `ret` variable for error value Changes since RFC: * Move documentation patch before ethtool patch * Add nla_total_size() instead of sizeof() directly * Return an error code from linkstate_get_ext_state() * Remove SHORTED_CABLE, add CABLE_TEST_FAILURE instead * Check if the interface is administratively up before setting ext_state * Document all sub-states ==================== Signed-off-by: -
