>From my reading of the spec, this check should be in avrcp_dump()
function -- like you did for skipping non-panel subunit packets. This
is because in the not-implemented case, only the avctp + avrcp headers
are sent, with no operands inside.

In AVRCP 1.3, section 4.3.4:

"All of the operands are optional and are defined based on the values
of ctype, subunit_type, and opcode."

In case ctype == NOT_IMPLEMENTED, there isn't any operand.
