RE: IPv6 / ndp taking a long time to resolve in this weeks STABL

I haven't modified the ndp related code for quite a long time, but recently=
 have seen
some postings regarding incomplete ndp entries (still catching up on emails=
).

Changes committed in the past year or so were related to locking and memory=
 leak, not
functional updates.

I have seen this issue with ARP, where incoming ARP requests are not comple=
ting
the entries until an explicit outgoing packet is generated right after the
system boots.

Email me when you recreate the problem.
