dd937e32bd Make the ioctl() interface cleaner with regard to types: use size_t 
instead of int where the variable has to hold buffer lengths,
use u_int for things like number of network interfaces which
in principle can never be negative.

cd7a4fa6eb Silence a gcc-warning. Do this by inlining the macro-call. This is 
not very nice - the compiler should just silently optimize away the
unused else clause.

9b18b1f47d Hand the packet to bpf not only in the LLC/SNAP case, but for all 
connections. While this confuses tcpdump, it enables other applications
to see and analyze non-IP traffic (signalling, for example).

05ab0ba3b5 Allocate network interfaces from malloc() instead of using a zone. 
Usually one needs only a couple of them so using a zone is waste
of memory (esp. on multi-cpu systems).

b92ba02261 Remove the zone limits for all the zones used in the ATM code. 
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.

1cafed3941 Update netisr handling; Each SWI now registers its queue, and all queue 
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.

9967cafc49 Correct mbuf packet header propagation. Previously, packet headers 
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.
