From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sowmini Varadhan Subject: [PATCH net-next 0/3] sunvnet: Use multiple Tx queues. Date: Wed, 29 Oct 2014 15:27:21 -0400 Message-ID: <20141029192721.GE6582@oracle.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: netdev@vger.kernel.org To: davem@davemloft.net, sowmini.varadhan@oracle.com Return-path: Received: from aserp1040.oracle.com ([141.146.126.69]:41611 "EHLO aserp1040.oracle.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751226AbaJ2T10 (ORCPT ); Wed, 29 Oct 2014 15:27:26 -0400 Content-Disposition: inline Sender: netdev-owner@vger.kernel.org List-ID: 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 3, 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 a minor correction to a comment that has a typo in the RFC number cited for the challenge-ack generation. Patch 2 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 drivers/net/ethernet/sun/sunvnet.c | 95 +++++++++++++++++++++++++------------- drivers/net/ethernet/sun/sunvnet.h | 2 + net/ipv4/tcp_input.c | 2 +- 3 files changed, 67 insertions(+), 32 deletions(-) -- 1.8.4.2
