Subject: [net-next, v2, 0/2] enetc: support PTP Sync packet one-step timestamping
Date: Thu, 8 Apr 2021 19:13:48 +0800 [thread overview]
Message-ID: <20210408111350.3817-1-yangbo.lu@nxp.com> (raw)
This patch-set is to add one-step timestamping support for PTP Sync
packet. Since ENETC single-step register has to be configured dynamically
per packet for correctionField offeset and UDP checksum update, current
one-step timestamping packet has to be sent only when the last one
completes transmitting on hardware. So, on the TX the patch implements
below process:
- For one-step timestamping packet, queue to skb queue.
- Start a work to transmit skbs in queue.
- For other skbs, transmit immediately.
- mutex lock used to ensure the last one-step timestamping packet has
already been transmitted on hardware before transmitting current one.
Changes for v2:
- Rebased.
- Fixed issues from patchwork checks.
- netif_tx_lock for one-step timestamping packet sending.
