Subject: Re: [PATCH RFC v4 6/6] tun: add rx timestamp to the vnet header
Date: Mon, 26 Oct 2026 08:50:28 +0000 [thread overview]
Message-ID: <sashiko-outbox-184698@kernel.org> (raw)
In-Reply-To: <20261026-v6-7-topic-virtio-net-ptp-v4-6-008af03cd43b@pengutronix.de>
> Reference implementation of the device side of VIRTIO_NET_F_RX_TSTAMP: if
> the configured vnet_hdr_sz covers the tstamp field, write the current
> TAI time into the header when a packet is handed to userspace or vhost.
> __tun_vnet_hdr_put() now takes the full struct virtio_net_common_hdr
> and copies as much of it as vnet_hdr_sz holds.
>
> This is not intended to be merged. A full test needs a QEMU that knows
> the feature and sets the matching vnet_hdr_sz in
> virtio_net_set_mrg_rx_bufs(); see
> https://github.com/strumtrar/qemu/tree/v11.0.1/virtio-rx-stamps
