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.

- Fix problem described in PR #1079: _gethostbynisaddr() doesn't
work. Make it accept the same arguments as all the other
gethostby*addr() functions and properly convert the supplied IP
address into a text string so that yp_match() can find it in the
hosts.byaddr map.
- Also fix potential memory leak: copy the results of yp_match() to
a static buffer and free the result (yp_match() returns dynamically
allocated memory).
ether_addr.c:
- Since I was in the neighborhood, fix ether_ntohost() and
ether_hostton() so that they don't bogusly for a free(result)
when yp_match() fails.
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.
found when the user specifies "mount -t type". Instead of printing
out one message for each path element (/sbin, /usr/sbin), it prints
out:
mount: exec mount_type not found in /sbin, /usr/sbin: No such file or directory
The code is quite long for such a stupid little piece of aesthesism
but it is very straghtforward so I guess it's ok. Besides, I don't
want to do a "char foo[100];" and have malloc break down when someone
decides to add a few more paths to a variable that's far apart from
this code. :)
By the way, there is no malloc() off-by-one error for the '\0' at the
end of the string although I don't explicitly add 1 to the length.
The code allocates strlen(path element)+2 bytes for each path element,
and doesn't use the last two bytes (for the delimiting ", ").

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.

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.

information. Also, print out the status along with the other
information as the default behavior.

I re-wrote alot of this, but the ideas are based on the code from the
most recent pccard-snapshot.
loader is also present in the coff loader. It was possible to get one
more page allocated than needed, which would cause brk()/malloc()/etc
to fail with ENOMEM when it tried to re-allocate the space.
Also, change a bcopy() from kernel to user space to a copyout().
