Ignore those for now. + +The whole story is a bit more complicated: It is possible to enable +debug output on SAM, which is sent via SSH command messages. By default +this output is sent to a debug connector, with its own target ID +(TID=0x03). It is possible to override the target of the debug output +and set it to the host/kernel driver. This, however, does not change the +original target ID of the message. Meaning, we receive messages with +TID=0x03 (debug) but expect to only receive messages with TID=0x00 +(host). + +The problem is that the different target ID also comes with a different +scope of request IDs. In particular, these do not follow the standard +event rules (i.e. do not fall into a set of small reserved values). +Therefore, current message handling interprets them as responses to +pending requests and tries to match them up via the request ID. However, +these debug output messages are not in fact responses, and therefore +this will at best fail to find the request and at worst pass on the +wrong data as response for a request. + +Therefore ignore any command messages not intended for us (host) for +now. We can implement support for the debug messages once we have a +better understanding of them. + +Note that this may also provide a bit more stability and avoid some +driver confusion in case any other targets want to talk to us in the +future, since we don't yet know what to do with those as well.
