Add new functions in DSA drivers to access hardware VLAN entries through
SWITCHDEV_OBJ_PORT_VLAN objects:

 - port_pvid_get() and vlan_getnext() to dump a VLAN
 - port_vlan_del() to exclude a port from a VLAN
 - port_pvid_set() and port_vlan_add() to join a port to a VLAN

The DSA infrastructure will ensure that each VLAN of the given range
does not already belong to another bridge. If it does, it will fallback
to software VLAN and won't program the hardware.

Like the ipv4 patch with a similar title, this adds a sysctl to allow
the user to change routing behavior based on whether or not the
interface associated with the nexthop was an up or down link.  The
default setting preserves the current behavior, but anyone that enables
it will notice that nexthops on down interfaces will no longer be
selected:

net.ipv6.conf.all.ignore_routes_with_linkdown = 0
net.ipv6.conf.default.ignore_routes_with_linkdown = 0
net.ipv6.conf.lo.ignore_routes_with_linkdown = 0
...

When the above sysctls are set, not only will link status be reported to
userspace, but an indication that a nexthop is dead and will not be used
is also reported.

1000::/8 via 7000::2 dev p7p1  metric 1024 dead linkdown  pref medium
1000::/8 via 8000::2 dev p8p1  metric 1024  pref medium
7000::/8 dev p7p1  proto kernel  metric 256 dead linkdown  pref medium
8000::/8 dev p8p1  proto kernel  metric 256  pref medium

fe80::/64 dev p7p1  proto kernel  metric 256 dead linkdown  pref medium
fe80::/64 dev p8p1  proto kernel  metric 256  pref medium

This also adds devconf support and notification when sysctl values
change.

Rocker driver tracks arp_tbl neighs to resolve IPv4 route nexthops.  The
driver uses NETEVENT_NEIGH_UPDATE for neigh adds and updates, but there is
no event when the neigh is removed from the device (such as when the device
goes admin down).  This patches hooks ndo_neigh_destroy so the driver can
know when a neigh is removed from the device.  In response, the driver will
purge the neigh entry from its internal tbl.

I didn't find an in-tree users of ndo_neigh_destroy, so I'm not sure if
this ndo is vestigial or if there are out-of-tree users.  In any case, it
does what I need here.  An alternative design would be to generate
NETEVENT_NEIGH_UPDATE event when neigh is being destroyed, setting state to
NUD_NONE so driver knows neigh entry is dead.

Enable smsc911x for use with ACPI

This set of patches enables the front Ethernet port on the
ARM Juno development platform when used with an ACPI enabled kernel.

These patches covert the of_property* calls in the driver to the
DT/ACPI agnostic device_property* calls, and add the arm hardware
id to the acpi_match_table.

To support the above changes I copied a couple routines from
of_net into the properties.c file, and modified them to
be ACPI/DT agnostic. I'm not 100% sure this is the correct location
for these functions. But I think they are required to avoid having
a dozen different implementations scattered across assorted Ethernet
adapters that are being enabled to use ACPI properties.

In cases where the platform is providing this information rather

As per Am335x Errata [1] Advisory 1.0.9, The CPSW C0_TX_PEND and
C0_RX_PEND interrupt outputs provide a single transmit interrupt
that combines transmit channel interrupts TXPEND[7:0] and a
single receive interrupt that combines receive channel interrupts
RXPEND[7:0]. The TXPEND[0] and RXPEND[0] interrupt outputs are
connected to the ARM Cortex-A8 interrupt controller (INTC) rather
than the C0_TX_PEND and C0_RX_PEND interrupt outputs. So even
though CPSW interrupt is cleared by writing appropriate values to
EOI register the interrupt is not cleared in IRQ controller. So
interrupt is still pending and CPU is struck in ISR, the
workaround is to disable the interrupts in ARM irq controller.

When a system has multiple ethernet devices and during DHCP
request (for using NFS), the system waits only for HZ/2 which is
500mS before switching to another interface for DHCP.

There are some routers (Ex: Trendnet routers) which responds to
DHCP request at about 560mS. When the system has only one
ethernet interface there is no issue as the timeout is 2S and the
dev xid doesn't changes and only retries.

But when the system has multiple Ethernet like DRA74x with CPSW
in dual EMAC mode, the DHCP response is dropped as the dev xid
changes while shifting to the next device. So changing inter
device timeout to HZ (which is 1S).

Which looks correct according to the spec but only the first
(eth id 252)/last added rule for 10.0.0.3 will ever trigger.
As if filer did not treat the AND CLE as cluster start but
also kept AND-ing the rules.  We found no errata covering this.

The fact that nobody noticed (2) or (3) makes me think
that this feature is not very widely used and we should just
remove it.

At a cost of one line let's make sure .count is correct
when calling gfar_process_filer_changes().
