vxge: fix pktgen hangs (don't abuse skb->cb[])
This patch fixes a case in the transmit completion code which was resulting
in pktgen hanging at the end of a run. The cause is due to the fact that
the ->cb[] area of an skb cannot be used in a network driver's transmit
path, as that area belongs to the network protocol. Pktgen hangs, as it
sends out the same packet multiple times, and vxge's use of this area of
the skb for a temporary list can only add the packet to the temporary list
once (while it may be on the queue many times). The fix is to remove this
abuse of skb->cb[]. Instead, skb pointers are placed into a temporary
stack array, and then free outside of the tx lock. This retains the smp
optimization of doing dev_kfree_skb() outside of the tx lock.

ixgbe: allow vlan egress priority mapping in DCB mode
The skb priority to vlan-qos egress mapping that can be configured using
set_egress_map with vconfig is overriden by the DCB code in the driver.
This patch allows this existing mechanism to work and will increase the
configuration flexibility of DCB mode on Linux.
A hierarchy of configuration is:
1. Modifies the ixgbe_select_queue() routine for DCB mode to return the
priority value from the VLAN tag. It will normally be zero, unless the egress
priority map has modified it. This will get packets into the correct queue and
result in the queue_mapping field being set correctly.
2. Any tc filter which modifies queue_mapping will be honored, as the filters
are handled after the vlan egress map is handled.

cfg80211: do not iterate over rdev list on country IE hint
Simplify the country IE hint code by just bailing out if
a previous country IE has been issued. We currently just trust
the first AP we connect to on any card. The idea was to perform
conflict resolution within this routine but since we can no longer
iterate over the registered device list here we leave conflict
resolution to be dealt with at a later time on the workqueue.
This code has no functional changes other than saving us an
interation over the registered device list when a second card
is connected, or you unplug and connect the same one, and a
country IE is received. This would have been done upon every
beacon received.

mac80211: fix powersave
Some of the recent MLME rework I did broke powersave
because the ps_sdata isn't assigned at the right time,
and the work item wasn't removed from the list before
calling ieee80211_recalc_ps(). To be more specific,
this broke the case where you'd enabled PS before
associating, either automatically or with iwconfig.
