Oliver Hartkopp 9c0c191d82 can: isotp: set max PDU size to 64 kByte
The reason to extend the max PDU size from 4095 Byte (12 bit length value)
to a 32 bit value (up to 4 GByte) was to be able to flash 64 kByte
bootloaders with a single ISO-TP PDU. The max PDU size in the Linux kernel
implementation was set to 8200 Bytes to be able to test the length
information escape sequence.

It turns out that the demand for 64 kByte PDUs is real so the value for
MAX_MSG_LENGTH is set to 66000 to be able to potentially add some checksums
to the 65.536 Byte block.
