exponential backoff timing for retransmissions, there is a higher probability
that the cache entry is removed resulting in the disruption of the existing
traffic.
Another significant benefit of delayed neighbor solicitation retransmission is
higher robustness against transient failures, such as spanning tree re-
convergence and other layer 2 issues that can take many seconds to resolve.
The exponential back-off calculation is
next retransmission timer =
(BACKOFF_MULTIPLE^solicit_attempt_num) *$RETRANS
jittered value.
The exponential backoff algorithm complies with draft-ietf-6man-impatient-
nud-02.
Increase this value when large numbers of neighbors are present or when
neighbors are not being discovered due to network events like spanning-tree
re-convergence.
