      net: netcp: Add Keystone NetCP core ethernet driver · 84640e27
      由 Karicheri, Muralidharan 提交于 
      The network coprocessor (NetCP) is a hardware accelerator available in
Keystone SoCs that processes Ethernet packets. NetCP consists of following
hardware components

 1 Gigabit Ethernet (GbE) subsystem with a Ethernet switch sub-module to
   send and receive packets.
 2 Packet Accelerator (PA) module to perform packet classification
   operations such as header matching, and packet modification operations
   such as checksum generation.
 3 Security Accelerator(SA) capable of performing IPSec operations on
   ingress/egress packets.
 4 An optional 10 Gigabit Ethernet Subsystem (XGbE) which includes a
   3-port Ethernet switch sub-module capable of 10Gb/s and 1Gb/s rates
   per Ethernet port.
 5 Packet DMA and Queue Management Subsystem (QMSS) to enqueue and dequeue
   packets and DMA the packets between memory and NetCP hardware components
   described above.

NetCP core driver make use of the Keystone Navigator driver API to allocate
DMA channel for the Ethenet device and to handle packet queue/de-queue,
Please refer API's in include/linux/soc/ti/knav_dma.h and
drivers/soc/ti/knav_qmss.h for details.

NetCP driver consists of NetCP core driver and at a minimum Gigabit
Ethernet (GBE) module (1) driver to implement the Network device function.
Other modules (2,3) can be optionally added to achieve supported hardware
acceleration function. The initial version of the driver include NetCP
core driver and GBE driver modules.

Please refer Documentation/devicetree/bindings/net/keystone-netcp.txt
for design of the driver.

      netns: add rtnl cmd to add and get peer netns ids · 0c7aecd4
      由 Nicolas Dichtel 提交于 
      With this patch, a user can define an id for a peer netns by providing a FD or a
PID. These ids are local to the netns where it is added (ie valid only into this
netns).

The main function (ie the one exported to other module), peernet2id(), allows to
get the id of a peer netns. If no id has been assigned by the user, this
function allocates one.

These ids will be used in netlink messages to point to a peer netns, for example
in case of a x-netns interface.
