Mac reassignments should only be done when not supported by the firmware. To
accomplish that, checking firmware capability bit to know whether we should
reassign macs in the driver.

The Firmware dynamically changes flow steering hash configuration from covering
L2 only to "full" L2/L3/L4 mode needed. The dynamic change allows the driver
to set hard coded hash configuration which is changed by the firmware from L2
to L2/L3/L4 when attaching the first L3/L4 flow steering rule and back to L2
when there are no more such rules.

make sure to remove the rules that were set through ethtool.

Destination mac is a mandatory specification for ip/udp steering rules.
When attaching multicast steering rules via ethtool the unicast mac of the
interface was added to the rule specification instead of the multicast mac.
The following commit sets the corresponding multicast mac for the rule multicast ip.

Supporting access to skb->pkt_type is a bit tricky if we want
to have a generic code, allowing pkt_type to be moved in struct sk_buff
pkt_type is a bit field, so compiler cannot really help us to find
its offset. Let's use a helper for this : It will throw a one time
message if pkt_type no longer starts at a byte boundary or is
no longer a 3bit field.

Makes more sense to have randomly generated address by default than to
have all zeroes. It also allows user to for example put the bond into
bridge without need to have any slaves in it.
Also note that this changes only behaviour of bonds with no slaves. Once
the first slave device is enslaved, its address will be used (no change
here).
Also, fix dev_assign_type values on the way.

Instead of jumping aroung bugs that are easily fixed just don't let them in:
affected drivers should be either fixed or have NETIF_F_HW_VLAN_FILTER
removed from advertised features.
Quick grep in drivers/net shows two drivers that have NETIF_F_HW_VLAN_FILTER
but not ndo_vlan_rx_add/kill_vid(), but those are false-positives (features
are commented out).
OTOH two drivers have ndo_vlan_rx_add/kill_vid() implemented but don't
advertise NETIF_F_HW_VLAN_FILTER. Those are:
+ethernet/cisco/enic/enic_main.c
+ethernet/qlogic/qlcnic/qlcnic_main.c

Pull powerpc fixes from Benjamin Herrenschmidt:
"Whenever you have a chance between two dives, you might want to
consider pulling my merge branch to pickup a few fixes for 3.8 that
have been accumulating for the last couple of weeks (I was myself
travelling then on vacation).
Nothing major, just a handful of powerpc bug fixes that I consider
worth getting in before 3.8 goes final."
And I'll have everybody know that I'm not diving for several days yet.

With lazy interrupt, we always call __check_irq_replaysome with
decrementers_next_tb to check if we need to replay timer interrupt.
So in hotplug case we also need to set decrementers_next_tb as MAX
to make sure __check_irq_replay don't replay timer interrupt
when return as we expect, otherwise we'll trap here infinitely.

In preempt case current arch_local_irq_restore() from
preempt_schedule_irq() may enable hard interrupt but we really
should disable interrupts when we return from the interrupt,
and so that we don't get interrupted after loading SRR0/1.

The calculation for the left shift of the mask OPROFILE_PM_PMCSEL_MSK has an
error. The calculation is should be to shift left by (max_cntrs - cntr) times
the width of the pmsel field width. However, the #define OPROFILE_MAX_PMC_NUM
was used instead of OPROFILE_PMSEL_FIELD_WIDTH. This patch fixes the
calculation.

commit f96972f2dc "kernel/sys.c: call disable_nonboot_cpus() in
kernel_restart()"
added a call to disable_nonboot_cpus() on kernel_restart(), which tries
to shutdown all the CPUs except the first one. The issue with the PA
Semi, is that it does not support CPU hotplug.
When the call is made to __cpu_down(), it calls the notifiers
CPU_DOWN_PREPARE, and then tries to take the CPU down.
One of the notifiers to the CPU hotplug code, is the cpufreq. The
DOWN_PREPARE will call __cpufreq_remove_dev() which calls
cpufreq_driver->exit. The PA Semi exit handler unmaps regions of I/O
that is used by an interrupt that goes off constantly
(system_reset_common, but it goes off during normal system operations
too). I'm not sure exactly what this interrupt does.
Running a simple function trace, you can see it goes of |
