Series [v2,01/12] can: Add LIN bus as CAN abstraction | expand

Commit Message

Christoph Fritz May 2, 2024, 7:55 a.m. UTC 
A LIN bus supports up to 64 identifiers in one byte. This commit adds a
special frame ID, beyond the actual LIN identifiers, for signaling RX
offload configuration requests. This ID will be utilized in future LIN
enhancements to the CAN broadcast manager.
