    Subject[PATCH v2 0/4] Up until now, there was no way to let the user select the layer at which time stamping occurs. The stack assumed that PHY time stamping is always preferred, but some MAC/PHY combinations were buggy.
    Date
    From: Kory Maincent <kory.maincent@bootlin.com>

    This series aims to allow the user to select the desired layer
    administratively.

    - Patch 1 refactors get_ts_info copy/paste code.

    - Patch 2 introduces sysfs files that reflect the current, static
    preference of PHY over MAC.

    - Patch 3 makes the layer selectable at run time.

    - Patch 4 fixes up MAC drivers that attempt to defer to the PHY layer.
    This patch is broken out for review, but it will eventually be
    squashed into Patch 3 after comments come in.

    Changes in v2:
    - Move selected_timestamping_layer variable of the concerned patch.
    - Use sysfs_streq instead of strmcmp.
    - Use the PHY timestamp only if available.

    Richard Cochran (4):
    net: ethtool: Refactor identical get_ts_info implementations.
    net: Expose available time stamping layers to user space.
    net: Let the active time stamping layer be selectable.
    net: fix up drivers WRT phy time stamping
