Ira W. Snyder 30df5888e4 can: janz-ican3: avoid firmware lockup caused by infinite bus error quota ... If the bus error quota is set to infinite and the host CPU cannot keep up, the Janz VMOD-ICAN3 firmware will stop responding to control messages until the controller is reset. The firmware will automatically stop sending bus error messages when the quota is reached, and will only resume sending bus error messages when the quota is re-set to a positive value. This limitation is worked around by setting the bus error quota to one message, and then re-setting the quota to one message every time a bus error message is received. By doing this, the firmware never stops responding to control messages. The CAN bus can be reset without a hard-reset of the controller card. Signed-off-by: Ira W.
