to see and analyze non-IP traffic (signalling, for example).

available under this tree.

These were a left over from when the private memory pools were
converted to use uma zones. The limit of UMA zones, however,
works differently. When a zone is limited to only one or two pages
than, on multi-cpu systems, processes can get stuck on the zonelimit,
because all remaining free items are in caches of other CPUs.
Also add rudimentary error handling in some places (panic) when a zone
cannot be created.
drain routines are done by swi_net, which allows for better queue control
at some future point. Packets may also be directly dispatched to a netisr
instead of queued, this may be of interest at some installations, but
currently defaults to off.

were sometimes propagated using M_COPY_PKTHDR which actually did
something between a "move" and a "copy" operation. This is replaced
by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it
from the source mbuf) and m_dup_pkthdr which copies the packet
header contents including any m_tag chain. This corrects numerous
problems whereby mbuf tags could be lost during packet manipulations.
These changes also introduce arguments to m_tag_copy and m_tag_copy_chain
to specify if the tag copy work should potentially block. This
introduces an incompatibility with openbsd which we may want to revisit.
Note that move/dup of packet headers does not handle target mbufs
that have a cluster bound to them. We may want to support this;
for now we watch for it with an assert.
Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.

all of these systems were changed to use UMA zones, there is no use for
the api any longer.

handler and the device attach handling.
- Change the related HARP netatm code to use UMA zone functions when
dealing with the zones that were formerly the ATM interface (hea, hfa)
storage pools.
- Have atm_physif_freenifs() now get passed an uma_zone_t so that we can
properly free the allocated NIF's back to their zone.
This should be the last commit to remove any code that makes use of the
netatm storage pool api. I will be removing the api code within the near
future.
