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,

most of the time there is no need to issue a single system call. Concerning

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

Instead of having the device that asynchronously notifies the frame receptions,

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.
