The DSCP Policy to assign to packets received for
the specified ToS codepoint. This is an index
into the hpSwitchCosDSCPPolicy table, or the value
255 indicating no DSCP Policy exists. The DSCP
policy is associated with an 802.1p priority value,
which will be inserted in the 802.1Q tag and will
cause the packet to be placed in the appropriate
outbound port queue. The DSCP policy value (a
Differentiated Services codepoint) will also
replace the incoming value of the Differentiated
Services field of the IP Type-of-Service byte.
