linux-stable.git/drivers/hv/ring_buffer.c, branch linux-3.8.y Linux kernel stable tree net/hyperv: Add flow control based on hi/low watermark 2012-04-03T21:47:15+00:00 Haiyang Zhang haiyangz@microsoft.com 2012-03-27T13:20:45+00:00 33be96e47cc27f2f1a753a0707b02a73df8c8d46 In the existing code, we only stop queue when the ringbuffer is full, so the current packet has to be dropped or retried from upper layer. This patch stops the tx queue when available ringbuffer is below the low watermark. So the ringbuffer still has small amount of space available for the current packet. This will reduce the overhead of retries on sending. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Reviewed-by: K. Y. Srinivasan <kys@microsoft.com> Signed-off-by: David S.

Or at least the core hyperv bus code, and the utility driver, the rest still have some review to get through by the various subsystem maintainers.
