Describes whether the node is blocked or not. There are three
possible integer values for this field: 0-notBlocked,
1-Blocked, 2-WouldBeBlocked. The WouldBeBlocked value is used
to represent a node that would be in the blocked state if the
SourceBlocker was enabled. A node can get into this state only
if the blocker is disabled. If the blocker is enabled at this
point, the node will be blocked, and a connection filter will
be put in place when the next packet is received from this
node.
