still is that the 'link state change' bit in the status block seems
to change state an awful lot. I have a workaround for this in place
now, but it needs more investigation. For the moment though, this
is enough to get the driver to work with this card.
made aware in jail environments. Supposedly something is broken, so
this should be backed out until further investigation proves otherwise,
or a proper fix can be provided.
This increases the number of concurrent outgoing connections from ~4000
to ~16000. Other OSes (Solaris, OS X, NetBSD) and many other NAT
products have already made this change without ill effects, so we
should not run into any problems.

method-based inter-process security checks. To do this, introduce
a new cr_seeotheruids(u1, u2) function, which encapsulates the
"see_other_uids" logic. Call out to this policy following the
jail security check for all of {debug,sched,see,signal} inter-process
checks. This more consistently enforces the check, and makes the
check easy to modify. Eventually, it may be that this check should
become a MAC policy, loaded via a module.

soon because it's just getting harder and harder to find switches
that correctly implement the GET ALL NEXT subcommands for the SNS
protocol.
Latch up result out pointer and set a busy flag when we're looking
at the response queue. This allows for a cleaner way to make sure
we don't get multiple CPUs trying to read the same response queue
entries.
Change how isp_handle_other_response returns values (clarity).
Make PORT UNAVAILABLE the same as PORT LOGOUT (force a LIP).
Do some formatting changes.

Instead of caching the ucred reference, just go ahead and eat the
decerement and increment of the refcount. Now that Giant is pushed down
into crfree(), we no longer have to get Giant in the common case. In the
case when we are actually free'ing the ucred, we would normally free it on
the next kernel entry, so the cost there is not new, just in a different
place. This also removse td_cache_ucred from struct thread. This is
still only done #ifdef DIAGNOSTIC.

1) If deleting an entry results in a chain of deleted slots ending in an
empty slot, then we can be a bit more aggressive about marking slots as
empty.
2) The last stage of the FNV hash is to xor the last byte of data
into the hash. This means that filenames which differ only in
the last byte will be placed close to one another in the hash
table, which forms longer chains. To work around this common
case, we also hash in the address of the dirhash structure.
