SCSI is fairly unique among the ethereal protocols in that it is sometimes normal for a PDU we receive back froma device to be truncated.
(report luns with allocation length 8 for example)
Therefore it is a bit wrong to mark these packets as [malformed packets]
Since they are truncated by scsi and this is NOTY an error condition.
Add a new exception type : ScsiBoundsError
If this exception is caught by packet-frame, then print an appropriate message
instead of [malformed packet]
For SCSI, add helper macros TRY_SCSI_SHORT_PACKET and END_...
If the packet was not short in the normal sense (snaplen < packetlen) then intercept the exception for BoundsError and rethrow it as ScsiBoundsError instead.
