*	DCB: fix kfree(skb)	Roel Kluin	2009-01-05	1	-7/+7
\| \| \| \| \| \| \|	Use kfree_skb instead of kfree for struct sk_buff pointers. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
*	net: add DCNA attribute to the BCN interface for DCB	Don Skidmore	2008-12-22	1	-2/+4
\| \| \| \| \| \| \| \| \| \| \| \|	Adds the Backward Congestion Notification Address (BCNA) attribute to the Backward Congestion Notification (BCN) interface for Data Center Bridging (DCB), which was missing. Receive the BCNA attribute in the ixgbe driver. The BCNA attribute is for a switch to inform the endstation about the physical port identification in order to support BCN on aggregated links.

*	net: fix DCB setstate to return success/failure	Don Skidmore	2008-12-22	1	-3/+2
\| \| \| \| \| \| \| \| \| \| \| \|	Data Center Bridging (DCB) had no way to know if setstate had failed in the driver. This patch enables dcb netlink code to handle the status for the DCB setstate interface. Likewise it allows the driver to return a failed status if MSI-X isn't enabled.

*	net: fix dcbnl_setnumtcs operation check	Don Skidmore	2008-12-15	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	dcbml_setnumtcs wasn't checking for the presence of the setnumtcs function. Instead, it was checking for setstate which was a bug.

*	DCB: fix kconfig option	Jeff Kirsher	2008-11-25	2	-8/+18
\| \| \| \| \| \| \| \| \|	Since the netlink option for DCB is necessary to actually be useful, simplified the Kconfig option. In addition, added useful help text for the Kconfig option. Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
*	DCB: Add support for DCB BCN	Alexander Duyck	2008-11-21	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.

*	DCB: Add interface to query the state of PFC feature.	Alexander Duyck	2008-11-21	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.

*	DCB: Add interface to query # of TCs supported by device	Alexander Duyck	2008-11-21	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).

*	ixgbe: this patch adds support for DCB to the kernel and ixgbe driver	Alexander Duyck	2008-11-21	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).
