ixgbe: this patch adds support for DCB to the kernel and ixgbe driver 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).

net: fix DCB setstate to return success/failure 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.

DCB: Add interface to query the state of PFC feature. Adds a netlink interface for Data Center Bridging (DCB) to get and set the enable state of the Priority Flow Control (PFC) feature.
