In BPDUs use configured Hello_Time, not received from other bridge

>> RSTP-8.1
Tue Apr 30 13:33:08 2013: TEST_DESCRIPTION
If the physical connectivity of the network or management
parameters change, new spanning tree information will propagate
rapidly. Each Bridge accepts better information from any Bridge on
a LAN or revised information from the prior Designated Bridge for
that LAN. Updated Configuration Messages are transmitted through
Designated Ports, until the leaves of the Spanning Tree defined
by a new configuration are reached.
AND
The designatedTimes (17.19.5) for each Port, set equal to
the value of rootTimes, except for the Hello Time component,
which is set equal to BridgeTime's Hello Time
