This maintenance request is a fork of request 0311 to register the
request against IEEE Std 802.1CB. The original rational is: Stream
filters with wildcard stream_handle specification and a non-wildcard
priority specification only allow definition of such stream filters
on a per Bridge component resolution due to the definition of the
managed objects (12.31). Any Port association from the 802.1CB stream
identification and indirectly available via the stream_handle is lost
for such stream filters, which makes the definition of such stream
filters questionable. The only reason I can imagine for such stream
filters would be some sort of per class isolation for undersized switch
fabrics, but this a) was not the intent of PSFP and b) is not an issue
that needs to be addressed by IEEE Std 802.1Q. However, just re-defining
semantics could break backwards compatibility, so this might not be
an option.
