Detailed Description

ICanPort over a Linux SocketCAN interface (can0, vcan0). Linux only.

Raw CAN socket in non-blocking mode. Send writes one frame; a full socket queue (EAGAIN / ENOBUFS) answers QueueFull and the reader thread reports TX-done as soon as the socket is writable again. Error frames (controller warning / passive, bus-off, restarted, and the TEC/REC bytes when the kernel provides them) drive Status(). Bus-off recovery is the kernel's job (ip link set canX type can restart-ms N), so Recover() only reports whether the interface is still bus-off.
