From: Nikolay Aleksandrov <nikolay at cumulusnetworks.com> This patch allows the user to set and retrieve speed and duplex of the virtio_net device via ethtool. Having this functionality is very helpful for simulating different environments and also enables the virtio_net device to participate in operations where proper speed and duplex are required (e.g. currently bonding lacp mode

Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone. This does that. Compile tested only, but I'd seriously wonder if this broke anything.

In looking at the code I realized that the last of the HAL depenencies were removed with this patch. So, I'm pushing an updated patch that contains none of the HAL code in it.

Hi: This series tries to implement tx batching support for vhost. This was done by using MSG_MORE as a hint for under layer socket. The backend (e.g tap) can then batch the packets temporarily in a list and submit it all once the number of bacthed exceeds a limitation. Tests shows obvious improvement on guest pktgen over over mlx4(noqueue) on host: Mpps -+%

This patch adds a 'hairpin' (also called 'reflective relay') mode port configuration to the Linux Ethernet bridge kernel module. A bridge supporting hairpin forwarding mode can send frames back out through the port the frame was received on. Hairpin mode is required to support basic VEPA (Virtual Ethernet Port Aggregator) capabilities. You can find additional information on VEPA

The following series adds 2 new flags to bridge. One flag allows the user to control whether mac learning is performed on the interface or not. By default mac learning is on. The other flag allows the user to control whether unicast traffic is flooded (send without an fdb) to a given unicast port. Default is on. Changes since v4: - Implemented Stephen's suggestions. Changes since v2: -

We can only process 1 packet at one time during sendmsg(). This often lead bad cache utilization under heavy load. So this patch tries to do some batching during rx before submitting them to host network stack. This is done through accepting MSG_MORE as a hint from sendmsg() caller, if it was set, batch the packet temporarily in a linked list and submit them all once MSG_MORE were cleared. Tests
