Ethernet phy update - 16: phy port cleanup

Added corrections in #provider #backbone #bridge ( #PBB ) #phy #port #handler routines in bridge module. Updated provider bridge virtual instance port ( #VIP ) and provider instance port ( #PIP ) #create / #remove routines in accordance with the latest phy framework. Also updated provider backbone bridge agent framework for general corrections. Removed obsolete phy related routines from the ethernet module.

Ethernet phy update - 15: phy port cleanup

Added corrections in #provider #bridge ( #PB ) #phy #port #handler routines in bridge module. Updated provider bridge internal LAN ( #ILAN ) - between provider edge port ( #PEP ) and customer network port ( #CNP) - #create / #remove routines. Also updated provider backbone bridge ( #PBB ) provider instance port ( #PIP ) #attach / #detach operations on with the #bridge #component and customer backbone port ( #CBP ) #activation handler.

Bridge CoS update - 12

Created default tables in ethernet module for #port #level #priority #code #point ( #PCP ) #encoding / #decoding configuration on #provider #bridges ( #PB ). These tables will help to fill PCP encoding / decoding configuration with their initial values. The default table will ensure that ingress CoS is used unaltered and egress CoS is also conveyed unaltered.

Bridge CoS update - 3

Added optimizations for #port #level #access #priority #remapping configuration on customer bridges. This will reduce the memory requirement for supporting access priority remapping configuration. The access priority remapping will enable to map #customer #CoS on frames to a different CoS value at the customer domain border, while sending data to the provider network. This is useful when the #SLA with the #provider #network requires specific kind of CoS mapping for required QoS treatment. The remapped CoS will be used int the provider network for effective #QoS treatment on the frame. By default, for a frame the egress CoS is send unaltered.
