this fixes a problem that anybody with vty access can panic the system.

Do a better job of argument parsing.
Don't permit ping -f to a multicast address (very antisocial).
Don't permit -L, -I, -T options with unicast addresses.
Ensure that we ask for only AF_INET addresses (should close PR#2584).
Return <sysexits.h> error codes for failures. Document this.
Fix man page to identify the author and put sections in correct order.
Strong 2.2 and 2.1.x candidate. Someone should review the patch before,
however.
The maintainer of the Perl5 port should probably introduce a similar patch
there.
The sequencer expects untagged transactions to have the SCBID of the
transaction in the "busy target" array. So, ensure that the busy entry
is up to date for the target in this case. The new identify code in the
sequencer that performs additional sanity checking got caught up when a
tagged transaction created an untagged request sense.
In ahc_handle_seqint, ensure that the target ID is taken from the right
place. In the case of a selection, the ID is in SCSIID. In the case of
a reconnection it is found in SELID.
missing-parentheses bug, but this exposed a misplaced vfs_busy_pages().
This bug cost a factor of 2.5-3 in nfsv3 write performance! It should
be fixed in 2.2.
Removed some debugging code that gets triggered often in normal
operation. There are still many backwards diagnostics (#define
DIAGNOSTIC gives no diagnostics).

Print the stack pointer together with the frame pointer in the trap,
syscall and interrupt messages. The frame pointer is not very useful
for locating syscall args since syscall functions don't have a frame
pointer.
Print all the numbers in the trap, syscall and interrupt messages in
the default radix. The syscall number was confusing because it was
printed in decimal.
Use %#n format more and 0x%x less. 0x%x of course doesn't work with
a variable radix. ddb is now fairly consistent about using %+#n to
print all numbers. It omits the '+' for signed numbers the '#' in a
few cases (e.g., for function args) to save space.

Fix a bug in the initialization of the busreset_args that left the B channel
args unitialized and the A channel ones initialized to B's vales. Oops.
If we get a NO_IDENT sequencer interrupt (the reconnecting target didn't
issue an identify or botched it), reset the bus instead of panicing. We
should be able to recover from this error.
In the AWAITING_MSG handler, order messages by severity. Since the message
we send is based on a flag on the SCB, it is possible, during error recovery,
to get more than one flag set. This is fine since any time a new flag is
set, it is meant to take us to a more draconian level of recovery. This
also ensures that we don't lose any "history" of what the command has gone
through.
When we reset the bus, reset the "send ordered tag" bitmask.
Clear some additional interrupt status when we perform a bus reset.
time that we really want to do this is when a bus reset causes the sequencer
to be reset and the kernel driver now handles this case.
Remove some reordering in the select2 routine that wasn't necessary.
It was an experimental fix for a race condition I fixed elsewhere, and
confused the code flow.
Don't bother looping on a parity error in the mesgout loop since we can't
see parity errors on out phases.
Clean up the mesgin_identify code. In the old days, we "snooped" for tag
messages and used this as an indicator of whether or not the target was
using tagged transactions. This forced the sequencer to ack the identify
before determining if a valid SCB matched the target meaning that an abort
message to handle this case might not be seen before the target entered a
data phase. Since we can determin the "tagged-ness" of a target by looking
it up in the array of busy targets (recently introduced), we can determine
this up front simplifying the search code as well as ensuring we can follow
the SCSI specs method for rejecting a reselection.
When an SCB is placed on the free list, set its SCB_TAG to SCB_LIST_NULL.
This makes it much easier for the kernel driver to find active SCBs on the
card during error recovery.
cruft and resulted in loading usually following a null pointer. Use
something closer to the pre-Lite2 code, including not making a copy of
the new filesystem's config info. Not making a copy also fixes a race
for loading and a memory leak for unloading.
Fixed unloading of vfs's. maxvfsconf wasn't maintained.
Look up the vfs to unload by name instead of by number. The numbers
should go away as soon as all mount utilities are converted.
