For AF_INET6 sockets, the value of struct ipv6_pinfo.ipv6only is
exported to userspace. It indicates whether a socket bound to in6addr_any
listens on IPv4 as well as IPv6. Since the socket is natively IPv6, it is not
listed by e.g. 'ss -l -4'.

This patch is accompanied by an appropriate one for iproute2 to enable
the additional information in 'ss -e'.

Current implementation of descriptor init procedure only takes
care about setting/clearing ownership flag in "des0"/"des1"
fields while it is perfectly possible to get unexpected bits
set because of the following factors:

 [1] On driver probe underlying memory allocated with
     dma_alloc_coherent() might not be zeroed and so
     it will be filled with garbage.

 [2] During driver operation some bits could be set by SD/MMC
     controller (for example error flags etc).

And unexpected and/or randomly set flags in "des0"/"des1"
fields may lead to unpredictable behavior of GMAC DMA block.

This change addresses both items above with:

 [1] Use of dma_zalloc_coherent() instead of simple
     dma_alloc_coherent() to make sure allocated memory is
     zeroed. That shouldn't affect performance because
     this allocation only happens once on driver probe.

 [2] Do explicit zeroing of both "des0" and "des1" fields
     of all buffer descriptors during initialization of
     DMA transfer.

And while at it fixed identation of dma_free_coherent()
counterpart as well.

====================
changes to make ipv4 routing table aware of next-hop link status

This series adds the ability to have the Linux kernel track whether or
not a particular route should be used based on the link-status of the
interface associated with the next-hop.

Before this patch any link-failure on an interface that was serving as a
gateway for some systems could result in those systems being isolated
from the rest of the network as the stack would continue to attempt to
send frames out of an interface that is actually linked-down.  When the
kernel is responsible for all forwarding, it should also be responsible
for taking action when the traffic can no longer be forwarded -- there
is no real need to outsource link-monitoring to userspace anymore.

This feature is only enabled with the new per-interface or ipv4 global
sysctls called 'ignore_routes_with_linkdown'.

net.ipv4.conf.all.ignore_routes_with_linkdown = 0
net.ipv4.conf.default.ignore_routes_with_linkdown = 0
net.ipv4.conf.lo.ignore_routes_with_linkdown = 0
...

When the above sysctls are set, the kernel will not only report to
userspace that the link is down, but it will also report to userspace
that a route is dead.  This will signal to userspace that the route will
not be selected.

With the new sysctls set, the following behavior can be observed
(interface p8p1 is link-down):

default via 10.0.5.2 dev p9p1
10.0.5.0/24 dev p9p1  proto kernel  scope link  src 10.0.5.15
70.0.0.0/24 dev p7p1  proto kernel  scope link  src 70.0.0.1
80.0.0.0/24 dev p8p1  proto kernel  scope link  src 80.0.0.1 dead linkdown
90.0.0.0/24 via 80.0.0.2 dev p8p1  metric 1 dead linkdown
90.0.0.0/24 via 70.0.0.2 dev p7p1  metric 2
90.0.0.1 via 70.0.0.2 dev p7p1  src 70.0.0.1
    cache
local 80.0.0.1 dev lo  src 80.0.0.1
    cache <local>
80.0.0.2 via 10.0.5.2 dev p9p1  src 10.0.5.15
    cache

While the route does remain in the table (so it can be modified if
needed rather than being wiped away as it would be if IFF_UP was
cleared), the proper next-hop is chosen automatically when the link is
down.  Now interface p8p1 is linked-up:

default via 10.0.5.2 dev p9p1
10.0.5.0/24 dev p9p1  proto kernel  scope link  src 10.0.5.15
70.0.0.0/24 dev p7p1  proto kernel  scope link  src 70.0.0.1
80.0.0.0/24 dev p8p1  proto kernel  scope link  src 80.0.0.1
90.0.0.0/24 via 80.0.0.2 dev p8p1  metric 1
90.0.0.0/24 via 70.0.0.2 dev p7p1  metric 2
192.168.56.0/24 dev p2p1  proto kernel  scope link  src 192.168.56.2
90.0.0.1 via 80.0.0.2 dev p8p1  src 80.0.0.1
    cache
local 80.0.0.1 dev lo  src 80.0.0.1
    cache <local>
80.0.0.2 dev p8p1  src 80.0.0.1
    cache

and the output changes to what one would expect.

If the global or interface sysctl is not set, the following output would
be expected when p8p1 is down:

default via 10.0.5.2 dev p9p1
10.0.5.0/24 dev p9p1  proto kernel  scope link  src 10.0.5.15
70.0.0.0/24 dev p7p1  proto kernel  scope link  src 70.0.0.1
80.0.0.0/24 dev p8p1  proto kernel  scope link  src 80.0.0.1 linkdown
90.0.0.0/24 via 80.0.0.2 dev p8p1  metric 1 linkdown
90.0.0.0/24 via 70.0.0.2 dev p7p1  metric 2

If the dead flag does not appear there should be no expectation that the
kernel would skip using this route due to link being down.

v2: Split kernel changes into 2 patches: first to add linkdown flag and
second to add new sysctl settings.  Also took suggestion from Alex to
simplify code by only checking sysctl during fib lookup and suggestion
from Scott to add a per-interface sysctl.  Added iproute2 patch to
recognize and print linkdown flag.

v3: Code cleanups along with reverse-path checks suggested by Alex and
small fixes related to problems found when multipath was disabled.

v4: Drop binary sysctls

v5: Whitespace and variable declaration fixups suggested by Dave

v6: Style changes noticed by Dave and checkpath suggestions.

v7: Last checkpatch fixup.

Though there were some that preferred not to have a configuration option
and to make this behavior the default when it was discussed in Ottawa
earlier this year since "it was time to do this."  I wanted to propose
the config option to preserve the current behavior for those that desire
it.  I'll happily remove it if Dave and Linus approve.

An IPv6 implementation is also needed (DECnet too!), but I wanted to
start with the IPv4 implementation to get people comfortable with the
idea before moving forward.  If this is accepted the IPv6 implementation
can be posted shortly.

There was also a request for switchdev support for this, but that will
be posted as a followup as switchdev does not currently handle dead
next-hops in a multi-path case and I felt that infra needed to be added
first.

FWIW, we have been running the original version of this series with a
global sysctl and our customers have been happily using a backported
version for IPv4 and IPv6 for >6 months.

When the above sysctls are set, will report to userspace that a route is
dead and will no longer resolve to this nexthop when performing a fib
lookup.  This will signal to userspace that the route will not be
selected.  The signalling of a RTNH_F_DEAD is only passed to userspace
if the sysctl is enabled and link is down.  This was done as without it
the netlink listeners would have no idea whether or not a nexthop would
be selected.   The kernel only sets RTNH_F_DEAD internally if the
interface has IFF_UP cleared.

With the new sysctl set, the following behavior can be observed

This bug pops up with NetworkManager on Fedora 21. NetworkManager tends to
stop the interface (nicvf_stop() is called) before changing settings. In
stopped state MAC cannot be sent to a PF. However, when the interface is
restarted (nicvf_open() is called), we ping the PF using NIC_MBOX_MSG_READY
message, and the PF replies back with old MAC address, overriding what we
had after MAC setting from userspace. As a result, we cannot set MAC
address using NetworkManager.

This patch introduces special tracking of MAC change in stopped state so
that the correct new MAC address is sent to a PF when interface is reopen.

2) netdev txq to priv sq (used @mlx5e_xmit())

Thanks to these static mappings, no more need for a separate implementation
of ndo_start_xmit when multiple TCs are configured.
We believe the performance improvement of such separation would be negligible, if any.

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    30-34			<< bridge side vlans
		 57

	sw1p1				<< device side vlans (missing)

	sw1p2    57

	sw1p2

	sw1p3

	sw1p4

	br0     None

(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:

	$ bridge -c vlan show
	port    vlan ids
	sw1p1    30-34			<< bridge side vlan
		 57

	sw1p1    30-34			<< device side vlans
		 57
		 3840 PVID

	sw1p2    57

	sw1p2    57
		 3840 PVID

	sw1p3    3842 PVID

	sw1p4    3843 PVID

	br0     None

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.

Use vid_begin/end to be consistent with BRIDGE_VLAN_INFO_RANGE_BEGIN/END.

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.

Changes since v1:
- Adapt to changes resulting from patch d42202dc ("net: stmmac:
dwmac-rk: Don't add function name in info or err messages")
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Add constants and callback functions for the dwmac on rk3368 socs.
As can be seen, the base structure is the same, only registers and
the bits in them moved slightly.

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.
