From: Kory Maincent <kory.maincent@xxxxxxxxxxx> 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.
