PATCH 2/8 vlan: Add support for net_devices_ops.ndo_fcoe_enable/_disable to VLAN

From: Yi Zou <[email protected]>

This adds implementation of the net_devices_ops.ndo_fcoe_enable/_disable to the VLAN driver. It checks if the real_dev has support for ndo_fcoe_enable/ ndo_fcoe_disable and if so, passes on to call the associated real_dev.

PATCH 3/8 ixgbe: Add support for the net_device_ops.ndo_fcoe_enable/disable to 82599

From: Yi Zou <[email protected]>

This adds support to the net_device_ops.ndo_fcoe_enable/disable for 82599. This consequently allows us to dynamically turn FCoE offload feature on or off upon incoming calls to ndo_fcoe_enable/disable. When this happens, FCoE offload features are enabled/disabled accordingly, and this is regardless of whether DCB being turned on or not.

PATCH 4/8 dcbnl: Add support for setapp/getapp commands to dcbnl

From: Yi Zou <[email protected]>

This patch adds dcbnl command definitions to support setapp/getapp functionality from the IEEE 802.1Qaz Data Center Bridging Capability Exchange protocol (DCBX) specification. Section 3.3 defines the application protocol and its 802.1p user priority in DCBX, which is implemented here as a pair of setapp/getapp commands in the kernel dcbnl for setting and retrieving the user priority for an given application protocol. The protocol is identified by the combination of an id and an idtype. Currently, when idtype is 0, the corresponding id gives the ether type of this protocol, e.g., for FCoE, it will be 0x8906; when idtype is 1, then the corresponding id gives the TCP or UDP port number.

For more information regarding DCBX spec., please refer to the following:
http://www.ieee802.org/1/files/public/docs2008/
az-wadekar-dcbx-capability-exchange-discovery-protocol-1108-v1.01.pdf
