Add support to replace an existing entry found in the
vxlan fdb database. The entry in question is identified
by its unicast mac address and the destination information
is changed. If the entry is not found, it is added in the
forwarding database. This is similar to changing an entry
in the neighbour table.

Multicast mac addresses can not be changed with the replace
option.

This is useful for virtual machine migration when the
destination of a target virtual machine changes. The replace
feature can be used instead of delete followed by add.

Yuchung Cheng ed08495c31 tcp: use RTT from SACK for RTO
If RTT is not available because Karn's check has failed or no
new packet is acked, use the RTT measured from SACK to estimate
the RTO. The sender can continue to estimate the RTO during loss
recovery or reordering event upon receiving non-partial ACKs.

This also changes when the RTO is re-armed. Previously it is
only re-armed when some data is cummulatively acknowledged (i.e.,
SND.UNA advances), but now it is re-armed whenever RTT estimator
is updated. This feature is particularly useful to reduce spurious
timeout for buffer bloat including cellular carriers [1], and
RTT estimation on reordering events.

Yuchung Cheng 59c9af4234 tcp: measure RTT from new SACK
Take RTT sample if an ACK selectively acks some sequences that
have never been retransmitted. The Karn's algorithm does not apply
even if that ACK (s)acks other retransmitted sequences, because it
must been generated by an original but perhaps out-of-order packet.
There is no ambiguity. In case when multiple blocks are newly
sacked because of ACK losses the earliest block is used to
measure RTT, similar to cummulative ACKs.

Such RTT samples allow the sender to estimate the RTO during loss
recovery and packet reordering events. It is still useful even with
TCP timestamps. That's because during these events the SND.UNA may
not advance preventing RTT samples from TS ECR (thus the FLAG_ACKED
check before calling tcp_ack_update_rtt()).  Therefore this new
RTT source is complementary to existing ACK and TS RTT mechanisms.

This patch does not update the RTO. It is done in the next patch.

Yuchung Cheng 5b08e47caf tcp: prefer packet timing to TS-ECR for RTT
Prefer packet timings to TS-ecr for RTT measurements when both
sources are available. That's because broken middle-boxes and remote
peer can return packets with corrupted TS ECR fields. Similarly most
congestion controls that require RTT signals favor timing-based
sources as well. Also check for bad TS ECR values to avoid RTT
blow-ups. It has happened on production Web servers.

   8) xen-netfront has to make two passes over an SKB to prepare it for

      can end up trying to build a MAX_SKB_FRAGS + 1 SKB which doesn't
      work out so well.  Fix from Jan Beulich with help and discussion

Pull x86 fixes from Peter Anvin:
 "Trying again to get the fixes queue, including the fixed IDT alignment
  patch.

  The UEFI patch is by far the biggest issue at hand: it is currently
  causing quite a few machines to boot.  Which is sad, because the only
  reason they would is because their BIOSes touch memory that has
  already been freed.  The other major issue is that we finally have
  tracked down the root cause of a significant number of machines
  failing to suspend/resume"

Linus Torvalds 4b8b8a4afa 3 bug fixes for md in 3.10
3.10 wasn't a good release for md.  The bio changes left a couple of
 bugs, and an md "fix" created another one.
 
 These three patches appear to fix the issues and have been tagged for
 -stable.

Eric Dumazet 3e3aac4975 vlan: fix a race in egress prio management
egress_priority_map[] hash table updates are protected by rtnl,
and we never remove elements until device is dismantled.

We have to make sure that before inserting an new element in hash table,
all its fields are committed to memory or else another cpu could
find corrupt values and crash.

Eric Dumazet d4b812dea4 vlan: mask vlan prio bits
In commit 48cc32d38a
("vlan: don't deliver frames for unknown vlans to protocols")
Florian made sure we set pkt_type to PACKET_OTHERHOST
if the vlan id is set and we could find a vlan device for this
particular id.

But we also have a problem if prio bits are set.

Steinar reported an issue on a router receiving IPv6 frames with a
vlan tag of 4000 (id 0, prio 2), and tunneled into a sit device,
because skb->vlan_tci is set.

Forwarded frame is completely corrupted : We can see (8100:4000)
being inserted in the middle of IPv6 source address :

16:48:00.780413 IP6 2001:16d8:8100:4000:ee1c:0:9d9:bc87 >
9f94:4d95:2001:67c:29f4::: ICMP6, unknown icmp6 type (0), length 64
       0x0000:  0000 0029 8000 c7c3 7103 0001 a0ae e651
       0x0010:  0000 0000 ccce 0b00 0000 0000 1011 1213
       0x0020:  1415 1617 1819 1a1b 1c1d 1e1f 2021 2223
       0x0030:  2425 2627 2829 2a2b 2c2d 2e2f 3031 3233

It seems we are not really ready to properly cope with this right now.

We can probably do better in future kernels :
vlan_get_ingress_priority() should be a netdev property instead of
a per vlan_dev one.

For stable kernels, lets clear vlan_tci to fix the bugs.
