NAME
     avbdiagnose – diagnostic tool for AVB.

SYNOPSIS
     avbdiagnose

DESCRIPTION
     The avbdiagnose tool is used to capture a snapshot of the current AVB
     system state and help diagnose common issues with AVB.

     avbdiagnose looks for the system to determine that it actually has AVB
     capable interfaces and that at least one of these has been enabled.

     avbdiagnose will produce a number of warnings which may not be errors
     depending on the setup of the system.  Things such as missing local or
     remote attributes for MSRP will be flagged as a warning but is not an error
     if the Mac is not sourcing or sinking streams as appropriate for the
     warning.

     avbdiagnose will flag potential errors and warnings and suggest filing a
     radar report at http://bugreporter.apple.com.  Please attach the generated
     file at /tmp/avbdiagnose-<date>.bz2 to the bug report. An error or warning
     report may be the result of a network device. Please use your best
     judgement before filing the bug report.
