Merge branch 'for-davem' of git://git./linux/kernel/git/bwh/sfc-next-2.6

sfc: Bump version to 3.1

All features originally planned for version 3.1 (and some that
weren't) have been implemented.

sfc: Remove configurable FIFO thresholds for pause frame generation

In Falcon we can configure the fill levels of the RX data FIFO which
trigger the generation of pause frames (if enabled), and we have
module parameters for this.

Siena does not allow the levels to be configured (or, if it does, this
is done by the MC firmware and is not configurable by drivers).

So far as I can tell, the module parameters are not used by our
internal scripts and have not been documented (with the exception of
the short parameter descriptions).  Therefore, remove them and always
initialise Falcon with the default values.

Remove the loopback condition, as STAT2.DEVPRST should be valid
regardless of any fault.

sfc: Read MC firmware version when requested through ethtool

We currently make no use of siena_nic_data::fw_{version,build} except
to format the firmware version for ethtool_get_drvinfo().  Since we
only read the version at start of day, this information is incorrect
after an MC firmware update.  Remove the cached version information
and read it via MCDI whenever it is requested.

Revert "sch_netem: Remove classful functionality"

Many users have wanted the old functionality that was lost
to be able to use pfifo as inner qdisc for netem. The reason that
netem could not be classful with the older API was because of the

a peek function, there is no longer a problem with using any
inner qdisc's.

ipv4: Rearrange how ip_route_newports() gets port keys.

ip_route_newports() is the only place in the entire kernel that
cares about the port members in the routing cache entry's lookup
flow key.

Therefore the only reason we store an entire flow inside of the
struct rtentry is for this one special case.

Rewrite ip_route_newports() such that:

1) The caller passes in the original port values, so we don't need
   to use the rth->fl.fl_ip_{s,d}port values to remember them.

2) The lookup flow is constructed by hand instead of being copied
   from the routing cache entry's flow.

Implemented igb_ndo_set_vf_bw function which is being used
by iproute2 tool. In addition, updated igb_ndo_get_vf_config function
to show the actual rate limit to the user.

The rate limitation can be configured only when the link is up.
The rate limit value can be ranged between 0 and actual
link speed measured in Mbps. A value of '0' disables the rate limit for
this specific VF.

iproute2 usage will be 'ip link set ethX vf Y rate Z'.
After the command is made, the rate will be changed instantly.
To view the current rate limit, use 'ip link show ethX'.

The rates will be zeroed only upon driver reload or a link speed change.

This feature is being supported only by 82576 device.

tipc: Avoid reliable broadcast preparation for NACK messages

Enhance TIPC to skip unnecessary (and, in some cases, redundant)
preparation work when sending a broadcast link NACK message, since this
preparation is only required for broadcast messages that are sent in a
reliable manner. This change also fixes a bug that caused NACK messages
to be improperly counted as "TX packets" in TIPC's broadcast link
statistics.

tipc: Remove unused message header field for requested number of links

Eliminates support for the "number of requested links" field in a neighbor
discovery message. This field was never used and has been removed from
the TIPC 2.0 protocol specification.

tipc: Remove support for per-connection message sequence numbering

Eliminates TIPC's prototype support for message sequence numbering
on routable connections (i.e. connections requiring more than one hop).
This capability isn't currently used, and can be removed since TIPC
only supports systems in which all inter-node communication can be
achieved in a single hop.

tipc: Add in missing lock during link initialization

Ensure that the routine that starts up processing on a newly created
link endpoint takes the spinlock of the node object that owns the link,
to prevent possible conflicts with processing involving other links
owned by that node object.

tipc: Fix port counter handling to correct congestion control

Modifies TIPC's congestion control between a connected port and its
peer so that it works as documented. The following changes have been
made:

1) The counter of the number of messages sent by a port now starts
   at zero, rather than one. This prevents the port from reporting port
   congestion one message earlier than it was supposed to.

2) The counter of the number of messages sent by a port is now
   incremented only if a non-empty message is sent successfully.
   This prevents the port from becoming permanently congested if
   too many send attempts are unsuccessful because of congestion
   (or other reasons). It also removes the risk that empty hand-
   shaking messages used during connection setup might cause the
   port to report congestion earlier than it was supposed to.

3) The counter of the number of unacknowledged messages received by
   a port controlled by an internal TIPC service is now incremented
   only if the message is non-empty, in order to be consistent with
   the aforementioned changes.

tipc: Minor optimization to topology service connection establishment

Eliminates a local iovec structure containing no data, which was
previously used during the establishment of a topology service connection,
since the same effect can be achieved by passing in a NULL pointer and
an iovec length of zero.

tipc: Set unused probe field of link protocol messages to defined value

Ensures that a link reset or activate message has a "probe" field
of zero. (This field is currently unused in these messages, but this
could potentially change in future versions of TIPC.)

tipc: Improve accuracy of link transmit queue maximum size statistic

Enhances TIPC's unicast and broadcast link code to update the transmit
queue maximum size counter in a single place, namely the routine that
adds messages to the queue. This ensures that the maximum size statistic
reported for unicast links is completely accurate, rather than being
partially based on statistical sampling.

The changes to link.h are just documenting the roles of the variables.

tipc: Eliminate unnecessary locking when starting topology service

Allows the broadcast link to track the node that is requesting a retransmit
in a new field dedicated to that purpose. This replaces the existing
mechanism that (ab)uses an existing node structure linked list field to do
the tracking.

that lives within an #if 0 ... #endif block.  If some of it is needed
in the future it can recovered out of history, but there is no need
for it to clutter up the active code base.
