net/hyperv: Add flow control based on hi/low watermark
In the existing code, we only stop queue when the ringbuffer is full,
so the current packet has to be dropped or retried from upper layer.
This patch stops the tx queue when available ringbuffer is below
the low watermark. So the ringbuffer still has small amount of space
available for the current packet. This will reduce the overhead of
retries on sending.

af_unix: reduce high order page allocations
unix_dgram_sendmsg() currently builds linear skbs, and this can stress
page allocator with high order page allocations. When memory gets
fragmented, this can eventually fail.
We can try to use order-2 allocations for skb head (SKB_MAX_ALLOC) plus
up to 16 page fragments to lower pressure on buddy allocator.
This patch has no effect on messages of less than 16064 bytes.
(on 64bit arches with PAGE_SIZE=4096)
For bigger messages (from 16065 to 81600 bytes), this patch brings
reliability at the expense of performance penalty because of extra pages
allocations.

ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4
In IPv4, if an RTA_IIF attribute is specified within an RTM_GETROUTE
message, then a route is searched as if a packet was received on the
specified 'iif' interface.
However in IPv6, RTA_IIF is not interpreted in the same way:
'inet6_rtm_getroute()' always calls 'ip6_route_output()', regardless the
RTA_IIF attribute.
As a result, in IPv6 there's no way to use RTM_GETROUTE in order to look
for a route as if a packet was received on a specific interface.
Fix 'inet6_rtm_getroute()' so that RTA_IIF is interpreted as "lookup a
route as if a packet was received on the specified interface", similar
to IPv4's 'inet_rtm_getroute()' interpretation.

net/garp: avoid infinite loop if attribute already exists
An infinite loop occurred if garp_attr_create was called with the values
of an existing attribute. This might happen if a previous leave request
for the attribute has not yet been followed by a PDU transmission (or,
if the application previously issued a join request for the attribute
and is now issuing another one, without having issued a leave request).
If garp_attr_create finds an existing attribute having the same values,
return the address to it. Its state will then get updated (i.e., if it
was in a leaving state, it will move into a non-leaving state and not
get deleted during the next PDU transmission).
To accomplish this fix, collapse garp_attr_insert into garp_attr_create
(which is its only caller).

bonding: emit event when bonding changes MAC
When a bonding device is configured with fail_over_mac=active,
we expect to see the MAC address of the new active slave as the source MAC
address after failover. But we see that the source MAC address is the MAC
address of previous active slave.
Emit NETDEV_CHANGEADDR event when bonding changes its MAC address, in order
to let arp_netdev_event flush neighbour cache and route cache.
How to reproduce this bug ?
-----------hostB----------------
hostA ----- switch ---|-- eth0--bond0(192.168.100.2/24)|

num_grat_arp=1
ifconfig bond0 192.168.100.2/24 up
ifenslave bond0 eth0
ifenslave bond0 eth1
then eth0 is the active slave, and MAC of bond0 is MAC of eth0.
2 on hostA, ping 192.168.100.2
3 on hostB,
tcpdump -i bond0 -p icmp -XXX
you will see bond0 uses MAC of eth0 as source MAC in icmp reply.
4 on hostB,
ifconfig eth0 down
tcpdump -i bond0 -p icmp -XXX (just keep it running in step 3)
you will see first bond0 uses MAC of eth1 as source MAC in icmp
reply, then it will use MAC of eth0 as source MAC.
