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 *);

Joel Soete reported oopses during pppoe over sundance NIC, caused by
a bug in skb allocation and dma mapping code, where skb_reserve()
bytes weren't taken into account. As a followup to the patch:

Joel Soete reported oopses at the beginning of pppoe connections since
v2.6.35. After debugging the bug was found in sundance skb allocation
and dma mapping code, where skb_reserve() bytes aren't taken into
account. This is an old bug, only uncovered by some change in 2.6.35.

This change forces the link down when a mailbox timeout has occurred.
Previously it was possible for a mailbox timeout to occur but for the
interface to stay up.  The problem with this was that it became possible
for an interface to stay up and miss multiple requests resulting in a
possible issue since the interface will be running in an unknown state.

  [SCSI] fix up documentation for change in ->queuecommand to lockless calling
  [SCSI] bfa: rename log_level to bfa_log_level

Low level drivers may behave differently depending on the current
link->lpm_policy.  During ata_eh_set_lpm(), DIPM enable commands are
issued after the successful completion of ap->ops->set_lpm(), which
means that the controller is already in the target state.  This causes
DIPM enable commands to be processed with mismatching controller power
state and link->lpm_policy value.

In ahci, link->lpm_policy is used to ignore certain PHY events if LPM
is enabled; however, as DIPM commands are issued with stale
link->lpm_policy, they sometimes end up triggering these conditions
and get aborted leading to LPM configuration failure.

Fix it by updating link->lpm_policy before issuing DIPM enable
commands.

ata_qc_complete() contains special handling for certain commands.  For
example, it schedules EH for device revalidation after certain
configurations are changed.  These shouldn't be applied to EH
commands but they were.

In most cases, it doesn't cause an actual problem because EH doesn't
issue any command which would trigger special handling; however, ACPI
can issue such commands via _GTF which can cause weird interactions.

Restructure ata_qc_complete() such that EH commands are always passed
on to __ata_qc_complete().
