Description john.r.fastabend 2012-04-10 21:59:40 EDT
The user may use dcbtool commands to clear advertise bits on CEE DCBX feature attributes (PFC, PG, APP). These are being lost across ifdown/ifup sequences and default values are being restored. The fix is to only set the values to defaults if the user has not explicitly enabled them. This default behavior was added to reduce DCBX configuration but missed this case.

The patch below resolves the issue:
