Since r186119 IP6 input counters for octets and packets were not
working anymore. In addition more checks and operations were missing.
In case lla_lookup results in a match, get the ifaddr to update the
statistics counters, and check that the address is neither tentative,
duplicate or otherwise invalid before accepting the packet. If ok,
record the address information in the mbuf. [ as is done in case
lla_lookup does not return a result and we go through the FIB ].
Document the mandatory argument to the arptimer() and
nd6_llinfo_timer() functions with a KASSERT().
Note: there is no need to return after panic.
In the legacy IP case, only assign the arg after the check,
in the IPv6 case, remove the extra checks for the table and
interface as they have to be there unless we freed and forgot
to cancel the timer. It doesn't matter anyway as we would
panic on the NULL pointer deref immediately and the bug is
elsewhere.
This unifies the code of both address families to some extend.

A previous change moved the GETATTR RPC for open() calls that hit in the
name cache up into nfs_lookup() instead of nfs_open(). Continue this
trend by flushing the attribute cache for leaf nodes in nfs_lookup() during
an open() if we do a LOOKUP RPC. For NFSv3 this should generally be a NOP
as the attributes are flushed before fetching the post-op attributes from
the LOOKUP RPC which most (all?) NFSv3 servers provide, so the post-op
attributes should populate the cache.
Now all NFS open() calls will always clear the cached attributes during the
nfs_lookup() prior to nfs_open() in the !NMODIFIED case to provide CTOC.
As a result, we can remove the conditional flushing of the attribute
cache from nfs_open().

"A receiving QoS STA is also required to keep only the most recent
cache entry per<Address 2, TID, sequence-number> triple, storing only
the most recently received fragment number for that triple. A receiving

To fix this, we just disable duplicate detection for multicast/broadcast
