* net/bridge: Add 'hairpin' port forwarding modeFischer, Anna2009-08-134-1/+23
| | | | | | | | | | | | | | | | | | | | | | | 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 here: http://tech.groups.yahoo.com/group/evb/ http://www.ieee802.org/1/files/public/docs2009/new-hudson-vepa_seminar-20090514d.pdf http://www.internet2.edu/presentations/jt2009jul/20090719-congdon.pdf An additional patch 'bridge-utils: Add 'hairpin' port forwarding mode' is provided to allow configuring hairpin mode from userspace tools.

* bnx2x: Configurable pause schemeEilon Greenstein2009-08-122-4/+12
| | | | | | | | | | | | When a given ring is running out of space, the FW can send pause towards the network. When working with multi-queues, when one queue is getting out of space it can block all other queues. The preferred scheme is to send pause frames only when running out of the shared internal chip buffers and if a given queue cannot place a packet on the host, it will drop it. Since some users might want to work in drop-less mode, allowing changing the behavior as a module parameter. Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.
