dcbnl: Add support for setapp/getapp to netdev dcbnl_rtnl_ops

2009-09-01T08:24:30+00:00

Adds support of dcbnl setapp/getapp to dcbnl_rtnl_ops in netdev to allow
LLDs to implement their corresponding dcbnl setapp/getapp ops to support
the IEEE 802.1Q DCBX setapp/getapp commands.

net: fix DCB setstate to return success/failure

2008-12-22T04:09:50+00:00

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 support for DCB BCN

2008-11-21T05:10:23+00:00

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.

2008-11-21T05:09:23+00:00

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

2008-11-21T05:08:19+00:00

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).

DCB: Add interface to query for the DCB capabilities of an device.

2008-11-21T05:05:08+00:00

Adds to the netlink interface for Data Center Bridging (DCB), allowing
the DCB capabilities supported by a device to be queried.

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

2008-11-21T04:52:10+00:00

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).
