1.2	27-May-2017	bouyer	branches: 1.2.6; 1.2.10; merge the bouyer-socketcan branch to HEAD. CAN stands for Controller Area Network, a broadcast network used in automation and automotive fields. For example, the NMEA2000 standard developped for marine devices uses a CAN network as the link layer. This is an implementation of the linux socketcan API: https://www.kernel.org/doc/Documentation/networking/can.txt you can also see can(4). This adds a new socket family (AF_CAN) and protocol (PF_CAN), as well as the canconfig(8) utility, used to set timing parameter of CAN hardware. Also inclued is a driver for the CAN controller found in the allwinner A20 SoC (I tested it with an Olimex lime2 board, connected with PIC18-based CAN devices). There is also the canloop(4) pseudo-device, which allows to use the socketcan API without CAN hardware. At this time the CANFD part of the linux socketcan API is not implemented. Error frames are not implemented either. But I could get the cansend and canreceive utilities from the canutils package to build and run with minimal changes. tcpudmp(8) can also be used to record frames, which can be decoded with etherreal.
1.1	17-Apr-2017	bouyer	branches: 1.1.2; file can_link.h was initially added on branch bouyer-socketcan.
1.1.2.2	18-Apr-2017	bouyer	Remove clt_clock_freq from user-supplied timing informations, it is defined by the brp.
1.1.2.1	17-Apr-2017	bouyer	Add infranstructure to configure timings from userland on a can interface. This uses the SIOCGDRVSPEC/SIOCSDRVSPEC ioctls. Compile-tested only.
1.2.10.2	03-Dec-2017	jdolecek	update from HEAD
1.2.10.1	27-May-2017	jdolecek	file can_link.h was added on branch tls-maxphys on 2017-12-03 11:39:03 +0000
1.2.6.2	28-Aug-2017	skrll	Sync with HEAD
1.2.6.1	27-May-2017	skrll	file can_link.h was added on branch nick-nhusb on 2017-08-28 17:53:12 +0000
