3ab332ee3f Fix bogus last commit - debugger_on_panic was referenced even when
not defined.  Another change clearly committed without testing! :-(

c8fcba1870 Remove reference to ac_ipaddr, which was being used to
determine if the interface had been assigned an IP address.
This code prevented the interface from receiving ethernet
broadcasts if it had no IP address assigned, and appeared
to be an optimization that is not completely needed.

203f0c075f Send ARP's for aliased subnets with the proper source address.
Get rid of ac->ac_ipaddr and arpwhohas() since they assume that
an interface has only one address.

9512fd2ec6 Make sure tcp_respond() always calls ip_output() with a valid
route pointer.  This has no effect in the current ip_output(),
but my version requires that ip_output() always be passed a route.

233e8c18e8 A number of performance-reducing flaws fixed based on comments
from Larry Peterson &co. at Arizona:

- Header prediction for ACKs did not exclude Fast Retransmit/Recovery.
- srtt calculation tended to get ``stuck'' and could never decrease
  when below 8.  It still can't, but the scaling factors are adjusted
  so that this artifact does not cause as bad an effect on the RTO
  value as it used to.

The paper also points out the incr/8 error that has been long since fixed,
and the problems with ACKing frequency resulting from the use of options
which I suspect to be fixed already as well (as part of the T/TCP work).

f3a4ca94cd Add support for /very/ experimental -e (exposure) option.
Add support for LKM operation.

Change M_NOWAIT on buffer memory allocation to M_WAIT in hopes we'll be
able to get ourselves a nice fat buffer from the kernel if we suspend.

Note: The LKM support looks kinda screwy in two areas, where I found
      problems with the kernel proper.  First, calling dev_attach()
      at module load time will cause a panic.  I haven't investigated.
      Secondly, I had to manually call qcam_drvinit() to register the
      device softc structure by hand at module load time.  This seems
      bogus,  it should be called as a core part of the module load
      process for character/block device drivers.

ede8dc43a2 Fixed unsigned longs that should have been vm_offset_t.
vm_offset_t is currently unsigned long but should probably be plain
unsigned for i386's to match the choice of minimal types to represent
for fixed-width types in Lite2.  Anyway, it shouldn't be assumed
to be unsigned long.

I only fixed the type mismatches that were detected when I changed
vm_offset_t to unsigned.  Only pointer type mismatches were detected.

ad5dd2341c Fix the problem that unmounting filesystems that are backed by a VMIO
device have reference count problems.  We mark the underlying object
ono-persistent, and account for the reference count that the VM system
maintainsfor the special device close.  This should fix the removable
device problem.

fe63158271 Changes to the Digi/Arnet SYNC driver:
1. Create 2 x 8k transmit buffer blocks in place of the 16k block previously.
   With this change the speed as tested with ttcp on a 2Mbit link went up
   from 206kbyte/s to 236kbyte/s.
2. Change the rest of the functions to also have the definition of the
   return value on a sepperate line.
3. Remove some unused variables.
4. Add code to recover from DMA underruns.
5. Reorder ar_get_packets() to handle errors better.
6. Only allocate a mbuf cluster if the data is more than the mbuf.

(and in a second diff in addition to the above)
7. Stops the occasional DMA underruns that occurred when 2 channels
   are running at 2Mbit/s.

dedc04fe95 Actually implement SA_RESETHAND - some of the sigaction code recognised it
but didn't actually do anything with it (*blush*).

This should fix bde's test case where the test program set SA_RESETHAND
and when reading it back, it was gone.

Tweak/optimize SA_NODEFER so that the implementation is a little simpler
and does not incur (slight) overhead for every signal at delivery time.

072b9b24e3 Fix ip option processing for raw IP sockets. This whole thing is a compromise
between ignoring options specified in the setsockopt call if IP_HDRINCL is set
(the UCB choice when VJ's code was brought in) vs allowing them (what everyone
else did, and what is assumed by programs everywhere...sigh).

Also perform some checking of the passed down packet to avoid running off
the end of a mbuf chain.

308c24ba5e This commit is as a result of a comment by Alan Cox (alc@cs.rice.edu)
regarding the "real" problem with maps that we have been having
over the last few weeks.  He noted that the first_free pointer was
left dangling in certain circumstances -- and he was right!!!   This
should fix the map problems that we were having, and also give us the
advantage of being able to simplify maps more aggressively.
