Commit "96793b482540f3a26e2188eaf75cb56b7829d3e3" (Add ICMPMsgStats
MIB (RFC 4293)) made a mistake.
In that patch, David L added a icmp_out_count() in
ip_push_pending_frames(), remove icmp_out_count() from
icmp_reply(). But he forgot to remove icmp_out_count() from
icmp_send() too. Since icmp_send and icmp_reply will call
icmp_push_reply, which will call ip_push_pending_frames, a duplicated
increment happened in icmp_send.
This patch remove the icmp_out_count from icmp_send too.

icmpv6_send() calls ip6_push_pending_frames() indirectly.
Both ip6_push_pending_frames() and icmpv6_send() increment
counter ICMP6_MIB_OUTMSGS.
This patch remove the increment from icmpv6_send.

When unregistering the rtnl_link_ops, all existing devices using
the ops are destroyed. With nested devices this may lead to a
use-after-free despite the use of for_each_netdev_safe() in case
the upper device is next in the device list and is destroyed
by the NETDEV_UNREGISTER notifier.
The easy fix is to restart scanning the device list after removing
a device. Alternatively we could add new devices to the front of
the list to avoid having dependant devices follow the device they
depend on. A third option would be to only restart scanning if
dev->iflink of the next device matches dev->ifindex of the current
one. For now this seems like the safest solution.
With this patch, the veth rtnl_link_ops unregistration can use
rtnl_link_unregister() directly since it now also handles destruction
of multiple devices at once.

When packets are flood-forwarded to multiple output devices, the
bridge-netfilter code reuses skb->nf_bridge for each clone to store
the bridge port. When queueing packets using NFQUEUE netfilter takes
a reference to skb->nf_bridge->physoutdev, which is overwritten
when the packet is forwarded to the second port. This causes
refcount unterflows for the first device and refcount leaks for all
others. Additionally this provides incorrect data to the iptables
physdev match.
Unshare skb->nf_bridge by copying it if it is shared before assigning
the physoutdev device.
Reported, tested and based on initial patch by
Jan Christoph Nordholz <hesso@pool.math.tu-berlin.de>.

We omit (or delay) sending NSes for known-to-unreachable routers (in
NUD_FAILED state) according to RFC 4191 (Default Router Preferences
and More-Specific Routes). But this is not fully compatible with RFC
4861 (Neighbor Discovery Protocol for IPv6), which does not remember
unreachability of neighbors.
So, let's avoid mixing sending algorithm of RFC 4191 and that of RFC
4861, and make the algorithm more friendly with RFC 4861 if RFC 4191
is disabled.
Issue was found by IPv6 Ready Logo Core Self_Test 1.5.0b2 (by TAHI
Project), and has been tracked down by Mitsuru Chinen
<mitch@linux.vnet.ibm.com>.

I noticed "ip route list" was slower than "cat /proc/net/route" on a
machine with a full Internet routing table (214392 entries : Special
thanks to Robert ;) )
This is similar to problem reported in commit
d8c9283089287341c85a0a69de32c2287a990e71 ("[IPV4] ROUTE: ip_rt_dump()
is unecessary slow")
Fix is to avoid scanning the begining of fz_hash table, but directly
seek to the right offset.
Before patch :
time ip route >/tmp/ROUTE
real 0m1.285s
user 0m0.712s
sys 0m0.436s
After patch
# time ip route >/tmp/ROUTE
real 0m0.835s
user 0m0.692s
sys 0m0.124s

Several of the Intel ethernet drivers keep an atomic counter used to
manage when to actually hit the hardware with a disable or an enable.
The way the net_rx_work() breakout logic works during a pending
napi_disable() is that it simply unschedules the poll even if it
still has work.
This can potentially leave interrupts disabled, but that is OK
because all of the drivers are about to disable interrupts
anyways in all such code paths that do a napi_disable().
Unfortunately, this trips up the semaphore used here in the Intel
drivers. If you hit this case, when you try to bring the interface
back up it won't enable interrupts. A reload of the driver module
fixes it of course.
So what we do is make sure all the sequences now go:
napi_disable();
atomic_set(&adapter->irq_sem, 0);
*_irq_disable();
which makes sure the counter is always in the correct state.

When looking for a conflicting connection the !sk->sk_bound_dev_if
check is performed only for live sockets, but not for timewait-ed.
This is not the case for ipv4, for __inet6_lookup_established in
both ipv4 and ipv6 and for other places that check for tw-s.
Was this missed accidentally? If so, then this patch fixes it and
besides makes use if the dif variable declared in the function.

The PDC202xx older devices do not support ATAPI DMA via the usual
interfaces. What documentation I have isn't sufficient to support DMA and
it isn't clear if the Windows drivers do this or it is possible at all.
(Neither do the drivers/ide old drivers)
So turn it ATAPI DMA off, these are disk optimised controllers.

wn3_config is shared by these cards; the way we deal with it is both bad C
(union abuse) and broken on big-endian. For 3c515 it's less serious (ISA
cards are quite rare outside of little-endian boxen), but 3c574 is a pcmcia
one and that'd better be endian-independent... Fix is the same in both
cases.

The driver sets up the hardware to accept a frame with max length
equal to MTU + Ethernet header + FCS + VLAN tag, but we neglect to
add the VLAN tag size to the ingress buffer. When a VLAN-tagged
frame arrives, the hardware passes it, but bad things happen
because the buffer is too small. This patch fixes that.

alb_fasten_mac_swap (actually rlb_teach_disabled_mac_on_primary)
requries RTNL and no other locks. This could cause dev_set_promiscuity

reflect proper reality of locking requirements.
