This patch allows the recently added backplane device IDs that support KR
to fail over to KX during link setup. This is accomplished by the new MAC
link setup function ixgbe_setup_mac_link_smartspeed(). Comments were also
updated to better document the reason for the delays chosen for KX, KX4, BX,
BX4 and KR connections.

(This patch fixes bug of commit f7734fdf61ec6bb848e0bafc1fb8bad2c124bb50
title "make TLLAO option for NA packets configurable")
When the IPV6 conf is used, the function sysctl_set_parent is called and the
array addrconf_sysctl is used as a parameter of the function.
The above patch added new conf "force_tllao" into the array addrconf_sysctl,
but the size of the array was not modified, the static allocated size is
DEVCONF_MAX + 1 but the real size is DEVCONF_MAX + 2, so the problem is
that the function sysctl_set_parent accessed wrong address.
I got the following information.

UDP_HTABLE_SIZE was initialy defined to 128, which is a bit small for
several setups.
4000 active UDP sockets -> 32 sockets per chain in average. An
incoming frame has to lookup all sockets to find best match, so long
chains hurt latency.
Instead of a fixed size hash table that cant be perfect for every
needs, let UDP stack choose its table size at boot time like tcp/ip
route, using alloc_large_system_hash() helper
Add an optional boot parameter, uhash_entries=x so that an admin can
force a size between 256 and 65536 if needed, like thash_entries and
rhash_entries.
dmesg logs two new lines :
[ 0.647039] UDP hash table entries: 512 (order: 0, 4096 bytes)
[ 0.647099] UDP Lite hash table entries: 512 (order: 0, 4096 bytes)
Maximal size on 64bit arches would be 65536 slots, ie 1 MBytes for non
debugging spinlocks.

I'm only seeing this on x86_64 systems, not on 32-bit with same

fixes the problem too.

This removes a redundancy in the CCID half-connection (hc) naming scheme:
* instead of 'hctx->tx_...', write 'hc->tx_...';
* instead of 'hcrx->rx_...', write 'hc->rx_...';
which works because the 'type' of the half-connection is encoded in the
'rx_' / 'tx_' prefixes.

This patch starts a less problematic naming convention for CCID structs.
The old naming convention used 'hc{tx,rx}->ccid?hc{tx,rx}->...' as
recurring prefixes, which made the code
* hard to write (not easy to fit into 80 characters);
* hard to read (most of the space is occupied by prefixes).
The new naming scheme:
* struct entries for the TX socket are prefixed by 'tx_';
* and those for the RX socket are prefixed by 'rx_'.
The identifiers then remain distinguishable when grep-ing through the tree:
(a) RX/TX sockets are distinguished by the naming scheme,
(b) individual CCIDs are distinguished by filename (ccid{2,3,4}.{c,h}).
This first patch implements the scheme for CCID-2.

Subject: [PATCH] ipv6: new sysctl for sending TLLAO with unicast NAs
Neighbor advertisements responding to unicast neighbor solicitations
did not include the target link-layer address option. This patch adds
a new sysctl option (disabled by default) which controls whether this
option should be sent even with unicast NAs.
The need for this arose because certain routers expect the TLLAO in
some situations even as a response to unicast NS packets.
Moreover, RFC 2461 recommends sending this to avoid a race condition
(section 4.4, Target link-layer address)

After updating firmware stored in flash, users may wish to reset the
relevant hardware and start the new firmware immediately. This should
not be completely automatic as it may be disruptive.
A selective reset may also be useful for debugging or diagnostics.
This adds a separate reset operation which takes flags indicating the
components to be reset. Drivers are allowed to reset only a subset of
those requested, and must indicate the actual subset. This allows the
use of generic component masks and some future expansion.

[RFC] pkt_sched: gen_estimator: Don't report fake rate estimators
We currently send TCA_STATS_RATE_EST elements to netlink users, even if no estimator
is running.
# tc -s -d qdisc
qdisc pfifo_fast 0: dev eth0 root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
Sent 112833764978 bytes 1495081739 pkt (dropped 0, overlimits 0 requeues 0)
rate 0bit 0pps backlog 0b 0p requeues 0
User has no way to tell if the "rate 0bit 0pps" is a real estimation, or a fake
one (because no estimator is active)
After this patch, tc command output is :
$ tc -s -d qdisc
qdisc pfifo_fast 0: dev eth0 root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
Sent 561075 bytes 1196 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
We add a parameter to gnet_stats_copy_rate_est() function so that
it can use gen_estimator_active(bstats, r), as suggested by Jarek.
This parameter can be NULL if check is not necessary, (htb for
example has a mandatory rate estimator)

In some cases there is not desirable to switch back to primary interface when
it's link recovers and rather stay with currently active one. We need to avoid
packetloss as much as we can in some cases. This is solved by introducing

active no matter what.

IPv6 Rapid Deployment (6rd; draft-ietf-softwire-ipv6-6rd) builds upon
mechanisms of 6to4 (RFC3056) to enable a service provider to rapidly
deploy IPv6 unicast service to IPv4 sites to which it provides
customer premise equipment. Like 6to4, it utilizes stateless IPv6 in
IPv4 encapsulation in order to transit IPv4-only network
infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6
prefix of its own in place of the fixed 6to4 prefix.
With this option enabled, the SIT driver offers 6rd functionality by
providing additional ioctl API to configure the IPv6 Prefix for in
stead of static 2002::/16 for 6to4.
Original patch was done by Alexandre Cassen <acassen@freebox.fr>
based on old Internet-Draft.

When routing daemon wants to enable forwarding of multicast traffic it
performs something like:
struct vifctl vc = {
.vifc_vifi = 1,
.vifc_flags = 0,
.vifc_threshold = 1,
.vifc_rate_limit = 0,
.vifc_lcl_addr = ip, /* <--- ip address of physical
interface, e.g. eth0 */
.vifc_rmt_addr.s_addr = htonl(INADDR_ANY),
};
setsockopt(fd, IPPROTO_IP, MRT_ADD_VIF, &vc, sizeof(vc));
This leads (in the kernel) to calling vif_add() function call which
search the (physical) device using assigned IP address:
dev = ip_dev_find(net, vifc->vifc_lcl_addr.s_addr);
The current API (struct vifctl) does not allow to specify an
interface other way than using it's IP, and if there are more than a
single interface with specified IP only the first one will be found.
The attached patch (against 2.6.30.4) allows to specify an interface
by its index, instead of IP address:
struct vifctl vc = {
.vifc_vifi = 1,
.vifc_flags = VIFF_USE_IFINDEX, /* NEW */
.vifc_threshold = 1,
.vifc_rate_limit = 0,
.vifc_lcl_ifindex = if_nametoindex("eth0"), /* NEW */
.vifc_rmt_addr.s_addr = htonl(INADDR_ANY),
};
setsockopt(fd, IPPROTO_IP, MRT_ADD_VIF, &vc, sizeof(vc));
