50fa67ff5f Move the lockops together with the interface -- they are needed 
only at runtime.

9ae53a340e Take kernel lock before passing data to if_input. This is in line 
with IPL_NET interrupts generally not being MPSAFE.

b97bdf9424 Include a timestamp in the frame header. When converting to pcap, 
it can give some idea of when packets were sent.

nb. it's the sending host's timestamp, not an observer timestamp
like in the typical pcap case.

ce68b7ae71 Include a pointer to the beginning of the buffer and add support 
to the packet dumper.  This helps in situations where the juicy
details are in a bus multiple generations old.

e2f111efb1 * remove some magic numbers from the code

855ec3e9a1 Change bus header a little: reserve only 32bits for the lock and 
use 32bit atomic ops to handle it.  Begin data from 0x10 instead
of 0x14.

6fe4bb4ba8 Support carp. It would be nice to support this as its own component, 
but there's about 1000 lines of #ifdef which disagree with my wish.

bcc65ff09f Split-off IPv4 re-assembly mechanism into a separate module. Abstract 
into ip_reass_init(), ip_reass_lookup(), etc (note: abstraction is not
yet complete).  No functional changes to the actual mechanism.

kernel module either be autoloaded from the host or the kernel
module ABI is not supported on the given arch.

bpf_attach.

510a73e003 Introduce RUMP_COMPONENT. It behaves mostly like a simplified 
module which is linked into the kernel and cannot be unloaded.
The main purpose is to get the proper constructors run and create
any /dev nodes necessary for said component.  Once more of the
kernel (e.g. networking stack and device drivers) are converted to
MODULE and devfs pops up from somewhere, rump components can be
retired.

643ba90bf0 Globally define -Wno-pointer-sign, as it has become a pointless 
exercise of "add it to every Makefile individually".

XXX: should autosynchronize with the rest of the kernel buildflags
in sys/conf/Makefile.kern.inc.

89a3fc440c Add components necessary for bpf support (commented out just for 
the sheer heck of it).

b014350f7f Redefine bpf linkage through an always present op vector, i.e. 
#if NBPFILTER is no longer required in the client.  This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached.  However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff.  ... and I'm not going to ponder the depths of unload
here.

Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

fbc989bbef Use linker script to make __start/stop_link_set_modules be present 
in libs built with binutils >=2.19.  This is a less error-prone
method than the previous where components had to be tagged in the
Makefile as modules (and if they weren't, things broke.  and vice
versa).
