This has never worked properly because wsize passed to
cxacru_cm() is incorrectly set to the number of values
instead of the data bytes. The maximum number of values
that can be set at once is 7 which means the device will
not get enough data to work with and none of the
configuration values will be used.At least one existing cxacru-cf.bin file contains invalid
data which will prevent the modem from syncing properly.Fixing it is likely to break existing systems, and the
new sysfs interface for setting configuration parameters
can provide the same functionality. A script is provided
to convert from the original format.Signed-off-by: Simon Arlott

The modem can be configured using CM_REQUEST_CARD_DATA_SET,
although CM_REQUEST_CARD_DATA_GET does not return any data.Tested by setting the modulation (0x0a) option.
There is a list of parameters in the following archive,
but the meaning of many of them is not well documented:
http://sourceforge.net/project/shownotes.php?release_id=301825This source also indicates that the highest parameter set
is 0x4a but this varies by model so an arbitrary limit of
0x7f has been used (the index is a 32-bit integer).Signed-off-by: Simon Arlott

This patch enables fast retransmissions after one dupACK for
TCP if the stream is identified as thin. This will reduce
latencies for thin streams that are not able to trigger fast
retransmissions due to high packet interarrival time. This
mechanism is only active if enabled by iocontrol or syscontrol
and the stream is identified as thin.Signed-off-by: Andreas Petlund

This patch will make TCP use only linear timeouts if the
stream is thin. This will help to avoid the very high latencies
that thin stream suffer because of exponential backoff. This
mechanism is only active if enabled by iocontrol or syscontrol
and the stream is identified as thin. A maximum of 6 linear
timeouts is tried before exponential backoff is resumed.Signed-off-by: Andreas Petlund

This fixes a problem in the DCCP getsockopt() API: currently there is no way
for a user to a priori know the number of built-in CCIDs, other than trying
DCCP_SOCKOPT_AVAILABLE_CCIDS in a loop, incrementing the option length until
EINVAL is no longer returned.This patch truncates the array to the user-provided length. No copy is made

If the per device ARP_ACCEPT option is enable, currently we only allow
creating new ARP cache entries for response type gratuitous ARP.Allowing gratuitous ARP to create new ARP entries (not only to update
existing ones) is useful when we want to avoid unnecessary delays for
the first packet of a stream.This patch allows request type gratuitous ARP to create new ARP cache
entries as well. This is useful when we want to populate the ARP cache
entries for a large number of hosts on the same LAN.Signed-off-by: Octavian Purdila

This is to be used together with switch technologies, like RFC3069,
that where the individual ports are not allowed to communicate with
each other, but they are allowed to talk to the upstream router. As
described in RFC 3069, it is possible to allow these hosts to
communicate through the upstream router by proxy_arp'ing.This patch basically allow proxy arp replies back to the same
interface (from which the ARP request/solicitation was received).Tunable per device via proc "proxy_arp_pvlan":
/proc/sys/net/ipv4/conf/*/proxy_arp_pvlanThis switch technology is known by different vendor names:
- In RFC 3069 it is called VLAN Aggregation.
- Cisco and Allied Telesyn call it Private VLAN.
- Hewlett-Packard call it Source-Port filtering or port-isolation.
- Ericsson call it MAC-Forced Forwarding (RFC Draft).Signed-off-by: Jesper Dangaard Brouer

This patch provides infrastructure for machine translation of the
regulatory rules database used by CRDA into a C data structure.
It includes code for searching that database as an alternative
to dynamic regulatory rules updates via CRDA. Most people should
use CRDA instead of this infrastructure, but it provides a better
alternative than the WIRELESS_OLD_REGULATORY infrastructure (which
can now be removed).Signed-off-by: John W. Linville

Define sysctl (tcp_cookie_size) to turn on and off the cookie option
default globally, instead of a compiled configuration option.Define per socket option (TCP_COOKIE_TRANSACTIONS) for setting constant
data values, retrieving variable cookie values, and other facilities.Move inline tcp_clear_options() unchanged from net/tcp.h to linux/tcp.h,
near its corresponding struct tcp_options_received (prior to changes).This is a straightforward re-implementation of an earlier (year-old)
patch that no longer applies cleanly, with permission of the original
author (Adam Langley):http://thread.gmane.org/gmane.linux.network/102586

Subject: [PATCH] ipv6: new sysctl for sending TLLAO with unicast NAsNeighbor 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

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
primary_reselect option. Note that enslaved primary slave is set as current
active no matter what.Patch modified by Jay Vosburgh as follows: fixed bug in action
after change of option setting via sysfs, revised the documentation
update, and bumped the bonding version number.Signed-off-by: Jiri Pirko

It is not currently possible to instruct pktgen to use one selected tx queue.
When Robert added multiqueue support in commit 45b270f8, he added
an interval (queue_map_min, queue_map_max), and his code doesnt take
into account the case of min = max, to select one tx queue exactly.I suspect a high performance setup on a eight txqueue device wants
to use exactly eight cpus, and assign one tx queue to each sender.This patchs makes pktgen select the right tx queue, not the first one.
Also updates Documentation to reflect Robert changes.

This patch introduces a new sysctl option to make IPv4 Address Scoping
configurable .In networking environments where DNAT rules in iptables prerouting
chains convert destination IP's to link-local/private IP addresses,
SCTP connections fail to establish as the INIT chunk is dropped by the
kernel due to address scope match failure.
For example to support overlapping IP addresses (same IP address with
different vlan id) a Layer-5 application listens on link local IP's,
and there is a DNAT rule that maps the destination IP to a link local
IP. Such applications never get the SCTP INIT if the address-scoping
draft is strictly followed.This sysctl configuration allows SCTP to function in such
unconventional networking environments.Sysctl options:
0 - Disable IPv4 address scoping draft altogether
1 - Enable IPv4 address scoping (default, current behavior)
2 - Enable address scoping but allow IPv4 private addresses in init/init-ack
3 - Enable address scoping but allow IPv4 link local address in init/init-ackSigned-off-by: Bhaskar Dutta

Commit b00055aacdb172c05067612278ba27265fcd05ce " [NET] core: add
RFC2863 operstate" defined new interface flag values. Its
documentation specified that these flags could be accessed from user
space via SIOCGIFFLAGS. However, this does not work because the new
flags do not fit in that ioctl's argument width.Change the documentation to match the code's behavior. Also change
the source to explicitly show the truncation. This _should_ have no
effect on executable code, and did not with gcc 4.2.4 generating x86
code.A new ioctl could be defined to return all interface flags to user
space. However, since this has been broken for three years with no
one complaining, there doesn't seem much need. They are still
accessible via netlink.Reported-by: "Fredrik Arnerup"
