      dcbnl: adding DCBX engine capability · 6241b625
      Shmulik Ravid authored 
      Adding an optional DCBX capability and a pair for get-set routines for
setting the device DCBX mode. The DCBX capability is a bit field of
supported attributes. The user is expected to set the DCBX mode with a
subset of the advertised attributes.

This patch is dependent on the following patches:
[net-next-2.6 PATCH 1/3] dcbnl: add support for ieee8021Qaz attributes
[net-next-2.6 PATCH 2/3] dcbnl: add appliction tlv handlers
[net-next-2.6 PATCH 3/3] net_dcb: add application notifiers

      net_dcb: add application notifiers · 96b99684
      John Fastabend authored 
      DCBx applications priorities can be changed dynamically. If
application stacks are expected to keep the skb priority
consistent with the dcbx priority the stack will need to
be notified when these changes occur.

This patch adds application notifiers for the stack to register
with.

      dcbnl: add appliction tlv handlers · 9ab933ab
      John Fastabend authored 
      This patch adds application tlv handlers. Networking stacks
may use the application priority to set the skb priority of
their stack using the negoatiated dcbx priority.

This patch provides the dcb_{get|set}app() routines for the
stack to query these parameters. Notice lower layer drivers
can use the dcbnl_ops routines if additional handling is
needed. Perhaps in the firmware case for example

      dcbnl: add support for ieee8021Qaz attributes · 3e29027a
      John Fastabend authored 
      The IEEE8021Qaz is the IEEE standard version of CEE. The
standard has had enough significant changes from the CEE
version that many of the CEE attributes have no meaning
in the new spec or do not easily map to IEEE standards.

Rather then attempt to create a complicated mapping
between CEE and IEEE standards this patch adds a nested
IEEE attribute to the list of DCB attributes. The policy
is,

	[DCB_ATTR_IFNAME]
	[DCB_ATTR_STATE]
	...
	[DCB_ATTR_IEEE]
		[DCB_ATTR_IEEE_ETS]
		[DCB_ATTR_IEEE_PFC]
		[DCB_ATTR_IEEE_APP_TABLE]
			[DCB_ATTR_IEEE_APP]
			...

The following dcbnl_rtnl_ops routines were added to handle
the IEEE standard,

	int (*ieee_getets) (struct net_device *, struct ieee_ets *);
	int (*ieee_setets) (struct net_device *, struct ieee_ets *);
	int (*ieee_getpfc) (struct net_device *, struct ieee_pfc *);
	int (*ieee_setpfc) (struct net_device *, struct ieee_pfc *);
	int (*ieee_getapp) (struct net_device *, struct dcb_app *);
	int (*ieee_setapp) (struct net_device *, struct dcb_app *);
