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

counters and cleaned up unused TCP segmentation counters. Removed
igc_power_down_link() and call igc_power_down_phy_copper_base()

Andre cleaned up timestamping by removing un-supported features and

instead of the skb for pending transmit timestamps. Refactored
igc_ptp_set_timestamp_mode() to simply the flow.

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

Currently, drivers can only tell whether the link is up/down using
LINKSTATE_GET, but no additional information is given.
Add attributes to LINKSTATE_GET command in order to allow drivers
to expose the user more information in addition to link state to ease
the debug process, for example, reason for link down state.
Extended state consists of two attributes - link_ext_state and
link_ext_substate. The idea is to avoid 'vendor specific' states in order
to prevent drivers to use specific link_ext_state that can be in the future
common link_ext_state.
The substates allows drivers to add more information to the common
link_ext_state. For example, vendor can expose 'Autoneg' as link_ext_state
and add 'No partner detected during force mode' as link_ext_substate.
If a driver cannot pinpoint the extended state with the substate
accuracy, it is free to expose only the extended state and omit the
substate attribute.
