Date: Thu, 01 May 2008 17:42:54 -0700 From: PJ Waskiewicz <peter.p.waskiewicz.jr@...el.com> To: jgarzik@...ox.com Cc: netdev@...r.kernel.org Subject: [ANNOUNCE] ixgbe: Data Center Bridging (DCB) support for ixgbe Jeff, This patchset introduces Data Center Bridging, a scheduling technology supported by Intel's 82598 silicon. The technology uses 802.1p VLAN priority tags to schedule and control traffic rates across an entire network. It also uses IEEE 802.1Qaz (priority grouping) and IEEE 802.1Qbb (priority flow control) technologies, in order to physically separate traffic flows that coexist on the same physical link. The technology is initially targeting storage traffic and regular LAN traffic on the same physical connection. Using priority flow control, one flow can be paused at the MAC level (same as 802.3 flow control) while not affecting other flows running at different priorities. The first patchset introduces a netlink interface for ixgbe, which is used to configure all the DCB parameters that come either from userspace, or from DCB-capable switch negotiation. The second patchset introduces the hardware initialization code to turn this whole technology on in the device. The third patchset implements the netlink interface and hardware init code, and enables DCB support in the driver.
