This patch implements couple of fixes to support ACPI for RGMII/SGMII0/XFI
interface of APM X-Gene SoC ethernet controller driver. This patch uses
the _SUN acpi object to fetch the port-id information whereas the FDT uses
port-id binding for port-id information.

Below case causes mii bus probe failed:
ifconfig eth0 down -> suspend/resume with Mega/fax mix off -> ifconfig eth0 up
In i.MX6SX/i.MX7D chip, Mega/fast mix off feature is supported that means most of
SOC power will be off including ENET MAC for power saving. Once ENET MAC power
off, all initialized MAC registers reset to default, so in the case, it must
init MAC prior to mii bus probe.

While IEEE and CEE use the same structure to store apps, the selector
and priority fields for both are different. Only the priority field is
explained, add documentation explaining how the selector field differs
for both.
cgdcbxd code shows an example of how selector fields differ.

This particular BUG_ON condition was checking for attr set err in the
COMMIT phase, which isn't expected (it's a driver bug if PREPARE phase is
OK but COMMIT fails). But BUG_ON() is too strong for this case, so change
to WARN(). BUG_ON() would be warranted if the system was corrupted beyond
repair, but this is not the case here.

switchdev; add VLAN support for port's bridge_getlink
One more missing piece of the puzzle. Add vlan dump support to switchdev
port's bridge_getlink. iproute2 "bridge vlan show" cmd already knows how
to show the vlans installed on the bridge and the device , but (until now)
no one implemented the port vlan part of the netlink PF_BRIDGE:RTM_GETLINK
msg. Before this patch, "bridge vlan show":
$ bridge -c vlan show
port vlan ids

sw1p1 << device side vlans (missing)
sw1p2 57

(When the port is bridged, the output repeats the vlan list for the vlans
on the bridge side of the port and the vlans on the device side of the
port. The listing above show no vlans for the device side even though they
are installed).
After this patch:

I re-used ndo_dflt_bridge_getlink to add vlan fill call-back func.
switchdev support adds an obj dump for VLAN objects, using the same
call-back scheme as FDB dump. Support included for both compressed and
un-compressed vlan dumps.

Remove handling of tx_ring in prb_setup_retire_blk_timer
for TPACKET_V3 because init_prb_bdqc is called only for zero tx_ring
and thus prb_setup_retire_blk_timer for zero tx_ring only.
And also in functon init_prb_bdqc there is no usage of tx_ring.
Thus removing tx_ring from init_prb_bdqc.

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.
No code is changed in this commit, just Kconfig help text.

net: stmmac: dwmac-rk: add support for rk3368
Apart from small cleanups, this series provides support for the dwmac
on the new rk3368 ARM64 soc.
Tested on a R88 board using a RMII phy.

The mac settings like RGMII/RMII, speeds etc are done in the so called
"General Register Files", contain numerous other settings as well and
always seem to change between Rockchip SoCs. Therefore abstract the
register accesses into a per-soc ops struct to make this reusable on
other Rockchip SoCs.

The first iteration of the dwmac-rk support did access an intermediate
clock directly below the pll selector. This was removed in a subsequent
revision, but the clock and one invocation remained. This results in
the driver trying to set the rate of a non-existent clock when the soc
and not some external source provides the phy clock for RMII phys.
So set the rate of the correct clock and remove the remaining now
completely unused definition.

Add code to nf_unregister_hook to flush the nf_queue when a hook is
unregistered. This guarantees that the pointer that the nf_queue code
retains into the nf_hook list will remain valid while a packet is
queued.
I tested what would happen if we do not flush queued packets and was
trivially able to obtain the oops below. All that was required was
to stop the nf_queue listening process, to delete all of the nf_tables,
and to awaken the nf_queue listening process.

Macvtap should be compatible with tuntap for
maximum number of queues.
commit 'baf71c5c1f80d82e92924050a60b5baaf97e3094 (tuntap:
Increase the number of queues in tun.)' removes
the limitations and increases number of queues in tuntap.
Now, Its safe to increase number of queues in Macvtap as well.
This patch also modifies 'macvtap_del_queues' function
to avoid extra memory allocation in stack.

BPF offers another way to generate latency histograms. We attach
kprobes at trace_preempt_off and trace_preempt_on and calculate the
time it takes to from seeing the off/on transition.
The first array is used to store the start time stamp. The key is the
CPU id. The second array stores the log2(time diff). We need to use
static allocation here (array and not hash tables). The kprobes
hooking into trace_preempt_on|off should not calling any dynamic
memory allocation or free path. We need to avoid recursivly
getting called. Besides that, it reduces jitter in the measurement.

When STP is running in user-space and querier is configured, the
querier timer is not started when a port goes to a non-blocking state.
This patch unifies the user- and kernel-space stp multicast port enable
path and enables it in all states different from blocking. Note that when a
port goes in BR_STATE_DISABLED it's not enabled because that is handled
in the beginning of the port list loop.

Actor and Partner details can be accessed via proc-fs, sys-fs
entries or netlink interface. These interfaces are world readable
at this moment. The earlier patch-series made the LACP communication
secure to avoid nuisance attack from within the same L2 domain but
it did not prevent "someone unprivileged" looking at that information
on host and perform the same act.
This patch essentially avoids spitting those entries if the user
in question does not have enough privileges.

net/macb: add sama5d2 support
This series is basically the support for another flavor of the GEM IP
configuration. It ended up being a series because of some little fixes made to
the binding documentation before adding the new compatibility string.

- add sama5d2 compatibility string to the binding documentation
