Pull networking changes from David Miller:

1) Allow to dump, monitor, and change the bridge multicast database
   using netlink.  From Cong Wang.

2) RFC 5961 TCP blind data injection attack mitigation, from Eric
   Dumazet.

3) Networking user namespace support from Eric W. Biederman.

4) tuntap/virtio-net multiqueue support by Jason Wang.

5) Support for checksum offload of encapsulated packets (basically,
   tunneled traffic can still be checksummed by HW).  From Joseph
   Gasparakis.

6) Allow BPF filter access to VLAN tags, from Eric Dumazet and
   Daniel Borkmann.

7) Bridge port parameters over netlink and BPDU blocking support
   from Stephen Hemminger.

8) Improve data access patterns during inet socket demux by rearranging
   socket layout, from Eric Dumazet.

9) TIPC protocol updates and cleanups from Ying Xue, Paul Gortmaker, and
   Jon Maloy.

10) Update TCP socket hash sizing to be more in line with current day
    realities.  The existing heurstics were choosen a decade ago.
    From Eric Dumazet.

11) Fix races, queue bloat, and excessive wakeups in ATM and
    associated drivers, from Krzysztof Mazur and David Woodhouse.

12) Support DOVE (Distributed Overlay Virtual Ethernet) extensions
    in VXLAN driver, from David Stevens.

13) Add "oops_only" mode to netconsole, from Amerigo Wang.

14) Support set and query of VEB/VEPA bridge mode via PF_BRIDGE, also
    allow DCB netlink to work on namespaces other than the initial
    namespace.  From John Fastabend.

15) Support PTP in the Tigon3 driver, from Matt Carlson.

16) tun/vhost zero copy fixes and improvements, plus turn it on
    by default, from Michael S. Tsirkin.

17) Support per-association statistics in SCTP, from Michele
    Baldessari.

And many, many, driver updates, cleanups, and improvements.  Too
numerous to mention individually.

Aeroflex Gaisler GRCAN and GRHCAN CAN controllers.
The GRCAN and CRHCAN CAN controllers are available in the GRLIB VHDL IP core
library.
Note: These properties are built from the AMBA plug&play in a Leon SPARC system
(the ordinary environment for GRCAN and GRHCAN). There are no dts files for
sparc.
Required properties:
- name : Should be "GAISLER_GRCAN", "01_03d", "GAISLER_GRHCAN" or "01_034"
- reg : Address and length of the register set for the device
- freq : Frequency of the external oscillator clock in Hz (the frequency of
the amba bus in the ordinary case)
- interrupts : Interrupt number for this device
Optional properties:
- systemid : If not present or if the value of the least significant 16 bits
of this 32-bit property is smaller than GRCAN_TXBUG_SAFE_GRLIB_VERSION
a bug workaround is activated.

In the other hand PACKET_MMAP is very efficient. PACKET_MMAP provides a size
configurable circular buffer mapped in user space that can be used to either
send or receive packets. This way reading packets just needs to wait for them,

transmission, multiple packets can be sent through one system call to get the
highest bandwidth.

int val = tpacket_version;
setsockopt(fd, SOL_PACKET, PACKET_VERSION, &val, sizeof(val));
getsockopt(fd, SOL_PACKET, PACKET_VERSION, &val, sizeof(val));
where 'tpacket_version' can be TPACKET_V1 (default), TPACKET_V2, TPACKET_V3.
TPACKET_V1:
- Default if not otherwise specified by setsockopt(2)
- RX_RING, TX_RING available
- VLAN metadata information available for packets
(TP_STATUS_VLAN_VALID)
TPACKET_V1 --> TPACKET_V2:
- Made 64 bit clean due to unsigned long usage in TPACKET_V1
structures, thus this also works on 64 bit kernel with 32 bit
userspace and the like
- Timestamp resolution in nanoseconds instead of microseconds
- RX_RING, TX_RING available
- How to switch to TPACKET_V2:
1. Replace struct tpacket_hdr by struct tpacket2_hdr
2. Query header len and save
3. Set protocol version to 2, set up ring as usual
4. For getting the sockaddr_ll,
use (void *)hdr + TPACKET_ALIGN(hdrlen) instead of
(void *)hdr + TPACKET_ALIGN(sizeof(struct tpacket_hdr))
TPACKET_V2 --> TPACKET_V3:
- Flexible buffer implementation:
1. Blocks can be configured with non-static frame-size
2. Read/poll is at a block-level (as opposed to packet-level)
3. Added poll timeout to avoid indefinite user-space wait
on idle links
4. Added user-configurable knobs:
4.1 block::timeout
4.2 tpkt_hdr::sk_rxhash
- RX Hash data available in user space
- Currently only RX_RING available

+ AF_PACKET fanout mode

The incoming packets are stored, by the DMA, in a list of pre-allocated socket
buffers in order to avoid the memcpy (Zero-copy).
4.3) Timer-Driver Interrupt
Instead of having the device that asynchronously notifies the frame receptions,
the driver configures a timer to generate an interrupt at regular intervals.
Based on the granularity of the timer, the frames that are received by the
device will experience different levels of latency. Some NICs have dedicated
timer device to perform this task. STMMAC can use either the RTC device or the
TMU channel 2 on STLinux platforms.
The timers frequency can be passed to the driver as parameter; when change it,
take care of both hardware capability and network stability/performance impact.
Several performance tests on STM platforms showed this optimisation allows to
spare the CPU while having the maximum throughput.
4.3) Interrupt Mitigation
The driver is able to mitigate the number of its DMA interrupts
using NAPI for the reception on chips older than the 3.50.
New chips have an HW RX-Watchdog used for this mitigation.
On Tx-side, the mitigation schema is based on a SW timer that calls the
tx function (stmmac_tx) to reclaim the resource after transmitting the
frames.
Also there is another parameter (like a threshold) used to program
the descriptors avoiding to set the interrupt on completion bit in
when the frame is sent (xmit).
Mitigation parameters can be tuned by ethtool.
