2009-03-01ixgbe: Add DCB for 82599, remove BCN supportPJ Waskiewicz
This patch adds the DCB (Data Center Bridging) support for 82599 hardware. This is similar to how the 82598 DCB code works. This patch also removes the BCN (Backwards Congestion Notification) netlink configuration code from the driver. BCN was a pre-standard congestion notification framework, and was not what the IEEE body decided upon for standard congestion management. QCN (802.1Qau), Quantized Congestion Notification is the accepted standard, which is not supported by 82599, hence we remove the support altogether.

2008-11-20DCB: Add support for DCB BCNAlexander Duyck
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.

2008-11-20ixgbe: this patch adds support for DCB to the kernel and ixgbe driverAlexander Duyck
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).
