When a user adds bridge neighbors, allow him to specify VLAN id.
If the VLAN id is not specified, the neighbor will be added
for VLANs currently in the ports filter list. If no VLANs are
configured on the port, we use vlan 0 and only add 1 entry.

Some multicast addresses are common to all macvlans,
so if a multicast message has a hash value collision, we
have to deliver a copy to all macvlans, adding significant
latency and possible packet drops if netdev_max_backlog
limit is hit.
Having a per macvlan hash function permits to reduce the
impact of hash collisions.

This adds FDB bridge ops to the macvlan device passthru mode.
Additionally a flags field was added and a NOPROMISC bit to
allow users to use passthru mode without the driver calling
dev_set_promiscuity(). The flags field is a u16 placed in a
4 byte hole (consuming 2 bytes) of the macvlan_dev struct.
We want to do this so that the macvlan driver or stack
above the macvlan driver does not have to process every
packet. For the use case where we know all the MAC addresses
of the endstations above us this works well.
This patch is a result of Roopa Prabhu's work. Follow up
patches are needed for VEPA and VEB macvlan modes.
v2: Change from distinct nopromisc mode to a flags field to
configure this. This avoids the tendency to add a new
mode every time we need some slightly different behavior.
v3: fix error in dev_set_promiscuity and add change and get
link attributes for flags.

When implementing VRRP v2 using macvlan several problems were
discovered. VRRP is weird in that all routers participating
in a redundant group use the same virtual MAC address.
Macvlan is a natural driver to use for this but it doesn't
work. The problem is that packets with a macvlan device's
source address are not received.
The problem is actually a regression that date back almost 2 years now.
The original problems started with:

- introduces __ethtool_get_settings which is called from ethtool code and
from drivers as well. Put ASSERT_RTNL there.
- dev_ethtool_get_settings() is replaced by __ethtool_get_settings()
- changes calling in drivers so rtnl locking is respected. In
iboe_get_rate was previously ->get_settings() called unlocked. This
fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same
problem. Also fixed by calling __dev_get_by_index() instead of
dev_get_by_index() and holding rtnl_lock for both calls.
- introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create()
so bnx2fc_if_create() and fcoe_if_create() are called locked as they
are from other places.

When the macvlan driver was extended to call unregisgter_netdevice_queue
in 23289a37e2, a use after free of struct
macvlan_port was introduced. The code in dellink relied on unregister_netdevice
actually unregistering the net device so it would be safe to free macvlan_port.
Since unregister_netdevice_queue can just queue up the unregister instead of
performing the unregiser immediately we free the macvlan_port too soon and
then the code in macvlan_stop removes the macaddress for the set of macaddress
to listen for and uses memory that has already been freed.
To fix this add a reference count to track when it is safe to free the macvlan_port
and move the call of macvlan_port_destroy into macvlan_uninit which is guaranteed
to be called after the final macvlan_port_close.

When the lower device has offloading capabilities, the packets checksums
are not computed. That leads to have any macvlan port in bridge mode to
not work because the packets are dropped due to a bad checksum.
If the macvlan is in bridge mode, the packet is forwarded to another
macvlan port and reach the network stack where it looks for a checksum
but this one was not computed due to the offloading of the lower device.
In this case, we have to set the packet with CHECKSUM_UNNECESSARY
when it is forwarded to a bridged port and restore the previous value of
ip_summed when the packet goes to the lowerdev.

With the current default 'vepa' mode, a KVM guest using virtio with
macvtap backend has the following limitations.
- cannot change/add a mac address on the guest virtio-net
- cannot create a vlan device on the guest virtio-net
- cannot enable promiscuous mode on guest virtio-net
To address these limitations, this patch introduces a new mode called
'passthru' when creating a macvlan device which allows takeover of the
underlying device and passing it to a guest using virtio with macvtap
backend.
Only one macvlan device is allowed in passthru mode and it inherits
the mac address from the underlying device and sets it in promiscuous
mode to receive and forward all the packets.

Mark Wagner reported OOM symptoms when sending UDP traffic over
a macvtap link to a kvm receiver.
This appears to be caused by the fact that macvtap packet queues
are unlimited in length. This means that if the receiver can't
keep up with the rate of flow, then we will hit OOM. Of course
it gets worse if the OOM killer then decides to kill the receiver.
This patch imposes a cap on the packet queue length, in the same
way as the tuntap driver, using the device TX queue length.
Please note that macvtap currently has no way of giving congestion
notification, that means the software device TX queue cannot be
used and packets will always be dropped once the macvtap driver
queue fills up.
This shouldn't be a great problem for the scenario where macvtap
is used to feed a kvm receiver, as the traffic is most likely
external in origin so congestion notification can't be applied
anyway.
Of course, if anybody decides to complain about guest-to-guest
UDP packet loss down the track, then we may have to revisit this.
Incidentally, this patch also fixes a real memory leak when
macvtap_get_queue fails.
Chris Wright noticed that for this patch to work, we need a
non-zero TX queue length. This patch includes his work to change
the default macvtap TX queue length to 500.

In commit be1f3c2c02 "net: Enable 64-bit
net device statistics on 32-bit architectures" I redefined struct
net_device_stats so that it could be used in a union with struct
rtnl_link_stats64, avoiding the need for explicit copying or
conversion between the two. However, this is unsafe because there is
no locking required and no lock consistently held around calls to
dev_get_stats() and use of the statistics structure it returns.
In commit 28172739f0 "net: fix 64 bit
counters on 32 bit arches" Eric Dumazet dealt with that problem by
requiring callers of dev_get_stats() to provide storage for the
result. This means that the net_device::stats64 field and the padding
in struct net_device_stats are now redundant, so remove them.
Update the comment on net_device_ops::ndo_get_stats64 to reflect its
new usage.
Change dev_txq_stats_fold() to use struct rtnl_link_stats64, since
that is what all its callers are really using and it is no longer
going to be compatible with struct net_device_stats.
Eric Dumazet suggested the separate function for the structure
conversion.

There is a small possibility that a reader gets incorrect values on 32
bit arches. SNMP applications could catch incorrect counters when a
32bit high part is changed by another stats consumer/provider.
One way to solve this is to add a rtnl_link_stats64 param to all
ndo_get_stats64() methods, and also add such a parameter to
dev_get_stats().
Rule is that we are not allowed to use dev->stats64 as a temporary
storage for 64bit stats, but a caller provided area (usually on stack)
Old drivers (only providing get_stats() method) need no changes.
