v2: moved tcp fix out of this series per David Miller feedback
The primary objective of this patch-set is to address the suggestion from
http://marc.info/?l=linux-netdev&m=140790778931563&w=2
With the changes in Patch 2, every vnet_port will get packets from
a single tx-queue, and flow-control/head-of-line-blocking is
confined to the vnet_ports that share that tx queue (as opposed to
flow-controlling *all* peers).
Patch 1 is an optimization that resets the DATA_READY bit when
we re-enable Rx interrupts. This optimization lets us exit quickly
from vnet_event_napi() when new data has not triggered an interrupt.
Sowmini Varadhan (3):
Correction to RFC number in comment
Reset LDC_EVENT_DATA_READY when napi completes.
Use one Tx queue per vnet_port

This looks great, series applied to net-next, thanks.
