Hello

I agree that the counting of the tagged cells is done by the at the input
port and thus these attribute should be renamed to :

atmVplStatTaggedIns
atmVclStatTaggedIns

and with an approriate change of the associated MIB text. 

This is the only logical way to trat these attributes. If e.g. the VCL or 
VPL belongs to an SPVC there will be no way to get the tagged counter of 
the opposite end of the SPVC !
