Subject: [PATCH RFC V1 net-next 0/4] Make MAC/PHY time stamping selectable
Date: Mon, 3 Jan 2022 15:25:51 -0800 [thread overview]
Message-ID: <20220103232555.19791-1-richardcochran@gmail.com> (raw)
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.
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.
Thanks,
Richard
