The value of tmnxMcPathVdoPlcyFCCBurst specifies the burst rate at
which the Fast Channel Change (FCC) server will send unicast data
to the client above the received rate to allow client to catch-up to
the multicast stream. The value is only applicable if
tmnxMcPathVdoPlcyFCCSvrMode is set to 'burst (1)' or 'hybrid (3)'
and tmnxMcPathVdoPlcyChlType is set to 'hd (2)', 'sd (3)',
or 'pip (4)'.
A default value of '25' indicates that FCC burst rate is set to 25%
above received rate.
