Subject: [PATCH v2 0/2] virtio-net: re-arm/re-schedule when tx_burst stops virtio_net_flush_tx()
Date: Fri, 14 Oct 2022 15:20:02 +0200 [thread overview]
Message-ID: <20221014132004.114602-1-lvivier@redhat.com> (raw)
When virtio_net_flush_tx() reaches the tx_burst value all the queue is
not flushed and nothing restart the timer or the bottom half function.
For BH, this is only missing in the virtio_net_tx_complete() function.
For the timer, the same fix is needed in virtio_net_tx_complete() but
it must be also managed in the TX timer function.
v2:
- fix also tx timer
Laurent Vivier (2):
virtio-net: fix bottom-half packet TX on asynchronous completion
virtio-net: fix TX timer with tx_burst
