      5Description:
      6		Value representing the can_id of mailbox 0.
      7
      8		Default: 0x7ff (standard frame)
      9
     10		Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in
     11		"AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the
     12		contents of mailbox 0 may be send under certain
     13		conditions (even if disabled or in rx mode).
     14
     15		The workaround in the errata suggests not to use the
     16		mailbox and load it with an unused identifier.
     17
     18		In order to use an extended can_id add the
     19		CAN_EFF_FLAG (0x80000000U) to the can_id. Example:
     20
     21		- standard id 0x7ff::
     22
     23		    echo 0x7ff      > /sys/class/net/can0/mb0_id
     24
     25		- extended id 0x1fffffff::
     26
     27		    echo 0x9fffffff > /sys/class/net/can0/mb0_id
