2008-11-20	DCB: Add support for DCB BCN	Alexander Duyck	1	-7/+167
	Adds an interface to configure the Backward Congestion Notification (BCN) feature. In a BCN capabale network, congestion notifications from congested points out in the network can cause the end station limit the rate of a given traffic flow.

2008-11-20	DCB: Add interface to query the state of PFC feature.	Alexander Duyck	1	-0/+43
	Adds a netlink interface for Data Center Bridging (DCB) to get and set the enable state of the Priority Flow Control (PFC) feature. Primarily, this is a way to turn off PFC in the driver while DCB remains enabled.

2008-11-20	DCB: Add interface to query # of TCs supported by device	Alexander Duyck	1	-0/+132
	Adds interface for Data Center Bridging (DCB) to query (and set if supported) the number of traffic classes currently supported by the device for the two (DCB) features: priority groups (PG) and priority flow control (PFC).

2008-11-20	ixgbe: this patch adds support for DCB to the kernel and ixgbe driver	Alexander Duyck	3	-0/+717
	This adds support for Data Center Bridging (DCB) features in the ixgbe driver and adds an rtnetlink interface for configuring DCB to the kernel. The DCB feature support included are Priority Grouping (PG) - which allows bandwidth guarantees to be allocated to groups to traffic based on the 802.1q priority, and Priority Based Flow Control (PFC) - which introduces a new MAC control PAUSE frame which works at granularity of the 802.1p priority instead of the link (IEEE 802.3x).
