Yes
Could you please give me some help?
> 1. you know a standard can frame mainly contains 11 ID and 8 byte data, according to the TSCAN1_manual,the SJA1000 supports dual-identifier mode. But each can frame has only one ID. Where comes double identifier?
Lincan (and the other ocera components) present APIs to the user. One of the structure members, canmsg_t.id is an unsigned long. This is all defined in the header canmsg.h

From userspace? The lincan module wont take too kindly to that ;)
Use the API

See above.
