hyperv: fix apparent cut-n-paste error in send path teardown

2014-06-17T04:36:13Z

c25aaf814a63: "hyperv: Enable sendbuf mechanism on the send path" added some teardown code that looks like it was copied from the recieve path above, but missed a variable name replacement. Signed-off-by: Dave Jones Signed-off-by: David S. Miller

hyperv: Add hash value into RNDIS Per-packet info

2014-05-23T18:49:00Z

It passes the hash value as the RNDIS Per-packet info to the Hyper-V host, so that the send completion notices can be spread across multiple channels. MS-TFS: 140273 Signed-off-by: Haiyang Zhang Signed-off-by: David S. Miller

net: get rid of SET_ETHTOOL_OPS

2014-05-13T21:43:20Z

net: get rid of SET_ETHTOOL_OPS Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone. This does that. Mostly done via coccinelle script: @@ struct ethtool_ops *ops; struct net_device *dev; @@ - SET_ETHTOOL_OPS(dev, ops); + dev->ethtool_ops = ops; Compile tested only, but I'd seriously wonder if this broke anything.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2014-05-12T17:19:14Z

Conflicts: drivers/net/ethernet/altera/altera_sgdma.c net/netlink/af_netlink.c net/sched/cls_api.c net/sched/sch_api.c The netlink conflict dealt with moving to netlink_capable() and netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations in non-init namespaces. These were simple transformations from netlink_capable to netlink_ns_capable. The Altera driver conflict was simply code removal overlapping some void pointer cast cleanups in net-next.

hyperv: Properly handle checksum offload

2014-04-30T20:12:23Z

Do checksum offload only if the client of the driver wants checksum to be offloaded. In V1 version of this patch, I addressed comments from Stephen Hemminger and Eric Dumazet . In this version of the patch I have addressed comments from David Miller. This patch fixes a bug that is exposed in gateway scenarios. Signed-off-by: K. Y.

hyperv: Enable sendbuf mechanism on the send path

2014-04-30T17:48:46Z

We send packets using a copy-free mechanism (this is the Guest to Host transport via VMBUS). While this is obviously optimal for large packets, it may not be optimal for small packets. Hyper-V host supports a second mechanism for sending packets that is "copy based". We implement that mechanism in this patch. In this version of the patch I have addressed a comment from David Miller. With this patch (and all of the other offload and VRSS patches), we are now able to almost saturate a 10G interface between Linux VMs on Hyper-V on different hosts - close to 9 Gbps as measured via iperf.

hyperv: Simplify the send_completion variables

2014-04-23T18:48:39Z

The union contains only one member now, so we use the variables in it directly. Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S. Miller

hyperv: Remove recv_pkt_list and lock

2014-04-23T18:48:39Z

Removed recv_pkt_list and lock, and updated related code, so that the locking overhead is reduced especially when multiple channels are in use. The recv_pkt_list isn't actually necessary because the packets are processed sequentially in each channel. It has been replaced by a local variable, and the related lock for this list is also removed. The is_data_pkt field is not used in receive path, so its assignment is cleaned up.

hyperv: Add support for virtual Receive Side Scaling (vRSS)

This feature allows multiple channels to be used by each virtual NIC. It is available on Hyper-V host 2012 R2. Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S. Miller
