Firmware does not support a periodic DMA of vadaptor-stats
on VFs, so only update the stats buffer when stats are
requested (when running "ethtool -S" or an ip/ifconfig
command that reports stats).

All interfaces will display vadaptor statistics, so set all the
relevant bits in the stats bitmask. Only functions with the
LINKCTRL flag will see other stats, including (per-port) MAC stats.
The vadaptor stats are from rx_unicast to tx_overflow.

The MAC stats are per-port and will only be displayed on the PF
with control of the link (one per physical port). Vadapter stats
will also be displayed for this PF, so distinguish the MAC stats
by adding a prefix of "port_".

rocker: enable by default untagged VLAN support
This patch set is a followup to Simon Horman's RFC patch:
[PATCH/RFC net-next] rocker: by default accept untagged packets
Now, on port probe, we install untagged VLAN (vid=0) support for each port
as the default. This is equivalent to the command:
bridge vlan add vid 0 dev DEV self
Accepting untagged VLAN pkts is a reasonable default, but the user could
override this with:
bridge vlan del vid 0 dev DEV self
With this, we no longer need 8021q module to install vid=0 when port interface
opens. In fact, we don't need support for legacy VLAN ndo ops at all since
they're superseded by bridge_setlink/dellink. So remove legacy VLAN ndo ops
support in driver. (The legacy VLAN ndo ops are supported by bonding/team
drivers, but don't fit into the transaction model offered by switchdev, so
switching all VLAN functions to bridge_setlink/dellink switchdev support gets
us stacked driver + transaction model support).

Remove support for legacy ndo ops
.ndo_vlan_rx_add_vid/.ndo_vlan_rx_kill_vid. Rocker will use
bridge_setlink/dellink exclusively for VLAN add/del operations.
The legacy ops are needed if using 8021q driver module to setup VLANs on
the port. But an alternative exists in using bridge_setlink/delink to
setup VLANs, which doesn't depend on 8021q module. So rocker will switch
to the newer setlink/dellink ops. VLANs can added/delete from the port,
regardless if port is bridged or not, using the bridge commands:
bridge vlan [add|del] vid VID dev DEV self
(Yes, I agree it's confusing to use the "bridge" command to set a VLAN on a
non-bridged port).
Using setlink/dellink over legacy ops let's us handle the stacked driver
case automatically. It's built-in. setlink also pass additional flags
(PVID, egress untagged) that aren't available with the legacy ops.

When the port joins a bridge, the port's internal VLAN ID needs to change
to the bridge's internal VLAN ID. Likewise, when leaving the bridge, the
internal VLAN ID reverts back the port's original internal VLAN ID. (The
internal VLAN ID is used by device to internally mark untagged pkts with
some VLAN, which will eventually be removed on egress...think PVID). When
the internal VLAN ID changes, we need to update the VLAN table entries and
the router MAC entries for IP/IPv6 to reflect the new internal VLAN ID.
This patch makes use of the common rocker_port_vlan_add/del functions to
make sure the tables are updated for the current internal VLAN ID.

When allocating the array of rocker port pointers, zero the array values so
we can test for !NULL to see if port is allocated/registered. We'll need
this later when installing untagged VLAN support for each port, during port
probe. It's a long story, but to install a VLAN (vid=0 for untagged, in
this case) on a port, we'll need to scan other ports to see if the VLAN
group for that VLAN has been setup. To scan the other ports, we need to
walk the port array.

The driver allocates one page for each buffer on the rx ring, which is
too much on architectures like ppc64 and can cause unexpected allocation
failures when the system is under stress. Now, we keep a memory pool
per queue, and if the architecture's PAGE_SIZE is greater than 4k, we
fragment pages and assign each 4k segment to a ring element, which
reduces the overall memory consumption on such architectures. This
helps avoiding errors like the example below:

When we scan a packet for GRO processing, we want to see the most
common packet types in the front of the offload_base list.
So add a priority field so we can handle this properly.
IPv4/IPv6 get the highest priority with the implicit zero priority
field.
Next comes ethernet with a priority of 10, and then we have the MPLS
types with a priority of 15.

is being accessed via a timer which is forbidden.

When we come to tear things down in netback_remove() and generate the
uevent it is possible that the xenstore directory has already been
removed (details below).
In such cases netback_uevent() won't be able to read the hotplug
script and will write a xenstore error node.
A recent change to the hypervisor exposed this race such that we now
sometimes lose it (where apparently we didn't ever before).
Instead read the hotplug script configuration during setup and use it
for the lifetime of the backend device.
The apparently more obvious fix of moving the transition to
state=Closed in netback_remove() to after the uevent does not work
because it is possible that we are already in state=Closed (in
reaction to the guest having disconnected as it shutdown). Being
already in Closed means the toolstack is at liberty to start tearing
down the xenstore directories. In principal it might be possible to
arrange to unregister the device sooner (e.g on transition to Closing)
such that xenstore would still be there but this state machine is
fragile and prone to anger...
A modern Xen system only relies on the hotplug uevent for driver
domains, when the backend is in the same domain as the toolstack it
will run the necessary setup/teardown directly in the correct sequence
wrt xenstore changes.

drivers/net/xen-netback/netback.c: In function ‘xenvif_tx_build_gops’:
drivers/net/xen-netback/netback.c:1253:8: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 5 has type ‘int’ [-Wformat=]
(txreq.offset&~PAGE_MASK) + txreq.size);
^
PAGE_MASK's type can vary by arch, so a cast is needed.

----
v2: Cast to unsigned long, since PAGE_MASK can vary by arch.

This partially reverts commit 1086bbe97a07 ("netfilter: ensure number of
counters is >0 in do_replace()") in net/bridge/netfilter/ebtables.c.
Setting rules with ebtables does not work any more with 1086bbe97a07 place.
There is an error message and no rules set in the end.
e.g.
~# ebtables -t nat -A POSTROUTING --src 12:34:56:78:9a:bc -j DROP
Unable to update the kernel. Two possible causes:
1. Multiple ebtables programs were executing simultaneously. The ebtables
userspace tool doesn't by default support multiple ebtables programs
running
Reverting the ebtables part of 1086bbe97a07 makes this work again.
