Expose reachable and retrans timer values in msecs instead of jiffies.
Both timer values are already exposed as msecs in the neighbour table
netlink interface.
The creation timestamp format with increased precision is kept but
cleaned up.

IFLA_PROTINFO exposes timer related per device settings in jiffies.
Change it to expose these values in msecs like the sysctl interface
does.
I did not find any users of IFLA_PROTINFO which rely on any of these
values and even if there are, they are likely already broken because
there is no way for them to reliably convert such a value to another
time format.

VORTEX_PCI() could return NULL so it needs to be casted before
accessing any member of struct pci_dev. This fixes following
build failure. Likewise VORTEX_EISA() was changed also.

But this device works better with dl2k driver.

netif_set_real_num_rx_queues() can decrement and increment
the number of rx queues. For example ixgbe does this as
features and offloads are toggled. Presumably this could
also happen across down/up on most devices if the available
resources changed (cpu offlined).
The kobject needs to be zero'd in this case so that the
state is not preserved across kobject_put()/kobject_init_and_add().
This resolves the following error report.
ixgbe 0000:03:00.0: eth2: NIC Link is Up 10 Gbps, Flow Control: RX/TX

I am not family with RealTek RTL-8139C+ series 10/100 PCI Ethernet driver.
I try to guess the meaning of RxProtoIP and IPFail.
RxProtoIP stands for received IPv4 packet that upper protocol is not tcp and udp.
!(status & IPFail) is true means that driver correctly to check checksum in IPv4 header.
If these are right, driver will set ip_summed with CHECKSUM_UNNECESSARY for other
upper protocol, e.g. sctp, igmp protocol. This will cause protocol stack ignores
checksum check for packets with invalid checksum.
This patch is only compile-test.

If r8196 received packets with invalid sctp/igmp(not tcp, udp) checksum, r8196 set skb->ip_summed

RxProtoIP stands for received IPv4 packet that upper protocol is not tcp and udp.

In rds_cmsg_rdma_args(), the user-provided args->nr_local value is
restricted to less than UINT_MAX. This seems to need a tighter upper
bound, since the calculation of total iov_size can overflow, resulting
in a small sock_kmalloc() allocation. This would probably just result
in walking off the heap and crashing when calling rds_rdma_pages() with
a high count value. If it somehow doesn't crash here, then memory
corruption could occur soon after.

When operating in a mode that initiates communication and using
HT40 we should fail if we cannot use both primary and secondary
channels to initiate communication. Our current ht40 allowmap
only covers STA mode of operation, for beaconing modes we need
a check on the fly as the mode of operation is dynamic and
there other flags other than disable which we should read
to check if we can initiate communication.
Do not allow for initiating communication if our secondary HT40
channel has is either disabled, has a passive scan flag, a
no-ibss flag or is a radar channel. Userspace now has similar
checks but this is also needed in-kernel.

The commit below added a new helper dev_ingress_queue to cleanly obtain the

commit 24824a09e35402b8d58dcc5be803a5ad3937bdba
Author: Eric Dumazet <eric.dumazet@gmail.com>
Date: Sat Oct 2 06:11:55 2010 +0000
net: dynamic ingress_queue allocation
However this include triggers issues for applications in userspace
which use the rtnetlink interfaces. Commonly this requires they include
'net/if.h' and 'linux/rtnetlink.h' leading to a compiler error as below:
In file included from /usr/include/linux/netdevice.h:28:0,
from /usr/include/linux/rtnetlink.h:9,
from t.c:2:

/usr/include/net/if.h:177:8: note: originally defined here
The new helper is only defined for the kernel and protected by __KERNEL__
therefore we can simply pull the include down into the same protected
section.

Currently, addrconf_ifdown does not delete statically configured IPv6
addresses when the interface is brought down. The intent is that when
the interface comes back up the address will be usable again. However,
this doesn't actually work, because the system stops listening on the
corresponding solicited-node multicast address, so the address cannot
respond to neighbor solicitations and thus receive traffic. Also, the
code notifies the rest of the system that the address is being deleted
(e.g, RTM_DELADDR), even though it is not. Fix it so that none of this
state is updated if the address is being kept on the interface.
Tested: Added a statically configured IPv6 address to an interface,
started ping, brought link down, brought link up again. When link came
up ping kept on going and "ip -6 maddr" showed that the host was still
subscribed to there

The RTO and timer modification code added to tcp_v4_err()
doesn't check sock_owned_by_user(), which if true means we
don't have exclusive access to the socket and therefore cannot
modify it's critical state.
Just skip this new code block if sock_owned_by_user() is true
and eliminate the now superfluous sock_owned_by_user() code
block contained within.

Now with improved comma support.
On parsing malformed X.25 facilities, decrementing the remaining length
may cause it to underflow. Since the length is an unsigned integer,
this will result in the loop continuing until the kernel crashes.
This patch adds checks to ensure decrementing the remaining length does
not cause it to wrap around.

There were some errors in the way that internal Gather Lists were being
translated into skb's. This also makes the VF Driver look more like the PF
Driver to facilitate easier comarison.
