====================
xen-netback: switch to NAPI + kthread 1:1 model
This series implements NAPI + kthread 1:1 model for Xen netback.
This model
- provides better scheduling fairness among vifs
- is prerequisite for implementing multiqueue for Xen network driver
The second patch has the real meat:
- make use of NAPI to mitigate interrupt
- kthreads are not bound to CPUs any more, so that we can take
advantage of backend scheduler and trust it to do the right thing
Benchmark is done on a Dell T3400 workstation with 4 cores, running 4
DomUs. Netserver runs in Dom0. DomUs do netperf to Dom0 with
following command: /root/netperf -H Dom0 -fm -l120
IRQs are distributed to 4 cores by hand in the new model, while in the
old model vifs are automatically distributed to 4 kthreads.

Add a SYNPROXY for netfilter. The code is split into two parts, the synproxy
core with common functions and an address family specific target.
The SYNPROXY receives the connection request from the client, responds with
a SYN/ACK containing a SYN cookie and announcing a zero window and checks
whether the final ACK from the client contains a valid cookie.
It then establishes a connection to the original destination and, if
successful, sends a window update to the client with the window size
announced by the server.
Support for timestamps, SACK, window scaling and MSS options can be
statically configured as target parameters if the features of the server
are known. If timestamps are used, the timestamp value sent back to
the client in the SYN/ACK will be different from the real timestamp of
the server. In order to now break PAWS, the timestamps are translated in

net: tcp_probe: allow more advanced ingress filtering by mark
Currently, the tcp_probe snooper can either filter packets by a given
port (handed to the module via module parameter e.g. port=80) or lets
all TCP traffic pass (port=0, default). When a port is specified, the
port number is tested against the sk's source/destination port. Thus,
if one of them matches, the information will be further processed for
the log.
As this is quite limited, allow for more advanced filtering possibilities
which can facilitate debugging/analysis with the help of the tcp_probe
snooper. Therefore, similarly as added to BPF machine in commit
7e75f93e
("pkt_sched: ingress socket filter by mark"), add the possibility to
use skb->mark as a filter.
If the mark is not being used otherwise, this allows ingress filtering
by flow (e.g. in order to track updates from only a single flow, or a
subset of all flows for a given port) and other things such as dynamic
logging and reconfiguration without removing/re-inserting the tcp_probe
module, etc. Simple example:
insmod net/ipv4/tcp_probe.ko fwmark=8888 full=1
...
iptables -A INPUT -i eth4 -t mangle -p tcp --dport 22 \
--sport 60952 -j MARK --set-mark 8888
[... sampling interval ...]
iptables -D INPUT -i eth4 -t mangle -p tcp --dport 22 \
--sport 60952 -j MARK --set-mark 8888
The current option to filter by a given port is still being preserved. A
similar approach could be done for the sctp_probe module as a follow-up.

rt2x00: rt2800lib: add rt2800_hw_beacon_base helper
The HW_BEACON_BASE() macro returns the base address
of a given beacon, however the returned values are
not usable on all chipsets. On devices which have
selectable shared memory parts, some beacon may be
located in the high part of the shared memory.
Instead of extending the already complicated macro,
add a new helper function and use that to get the
base address of a given beacon.
The actual patch contains no functional changes, the
helper function will be extended in a further patch
to handle different chipsets' requirements.

mac80211: fix change_interface queue assignments
Jouni reported that with mac80211_hwsim, multicast TX was causing
crashes due to invalid vif->cab_queue assignment. It turns out that
this is caused by change_interface() getting invoked and not having
the vif->type/vif->p2p assigned correctly before calling the queue
check (ieee80211_check_queues). Fix this by passing the 'external'
interface type to the function and adjusting it accordingly.
While at it, also fix the error path in change_interface, it wasn't
correctly resetting to the external type but using the internal one
instead.
Fortunately this affects on hwsim because all other drivers set the
vif->type/vif->p2p variables when changing iftype. This shouldn't
be needed, but almost all implementations actually do it for their
own internal handling.

openvswitch: Mega flow implementation
Add wildcarded flow support in kernel datapath.
Wildcarded flow can improve OVS flow set up performance by avoid sending
matching new flows to the user space program. The exact performance boost
will largely dependent on wildcarded flow hit rate.
In case all new flows hits wildcard flows, the flow set up rate is
within 5% of that of linux bridge module.
Pravin has made significant contributions to this patch. Including API
clean ups and bug fixes.
