SBC-CAN byte stuffing?

[ltzehan]

SBC-CAN is converting CAN messages and sending to UART in the following format:

+------+------+------+-------+--------------------------+
| 0xFE | 0xFE | <id> | <len> | <data> ... (<len> bytes) |
+------+------+------+-------+--------------------------+

Potentially has issues if serial connection to SBC is not synced properly and data field has back-to-back 0xFEs since current code does not handle this:
