- Use inet_ntoa(3) where it should have been used. This
part of code simply wasn't converted to the "new" style
after the routename() function was converted from the
protocol-generic version to protocol-specific version
in CSRG revision 5.6.

to be consistent with the -s flag. Updated documentation
on what this modifier does.
- Added the ``only'' keyword to the -s and -S flags, that
could be used to created "proxy-only" published entries.
Previously, arp(8) created an entry of this type only
in the absence of the route to a destination.

it from the Synopsis field. There's no reason for the subject to be
different, since all that does is cause confusion. Users may get
confused because they may think the subject and synopsis are supposed
to be different, and developers may get confused because it may look
like there are two different problems.

use of the extsts field in DMA descriptors. We need this to tell the chip
to calculate TCP/IP checksums in hardware on a per-packet basis.
- Fix the unions in DMA descriptor structures. Breakage on alpha led
me to realize I'd done it wrong the first time.
that device add/remove will work without usbd running. usbd is still
used for execing stuff, but that is all now. Ideally it could be replaced
by a devd some day. Until now, usbd had to be running so that the
USB_DISCOVER ioctl could be called to walk the tree when an attachment
status change was noticed.
Among the changes:
- when a detach happens, remove any pending 'attach' messages or the system
suffers from whiplash from exec moused / kill moused loops if you do lots
of attach/detach and later start usbd.
- tweaks related to kthread differences
- disable the select handler for the old interface (never return success).
I have not removed it yet or old usbd's will abort. That can get removed
later once usbd is cleaned up and things have stabilized for a few weeks.
- get Giant in the kthread.
- a couple of minor potential bug fixes (usb_nevents vs malloc failure etc)

One way we can reduce the amount of traffic we send in response to a SYN
flood is to eliminate the RST we send when removing a connection from
the listen queue. Since we are being flooded, we can assume that the
majority of connections in the queue are bogus. Our RST is unwanted
by these hosts, just as our SYN-ACK was. Genuine connection attempts
will result in hosts responding to our SYN-ACK with an ACK packet. We
will automatically return a RST response to their ACK when it gets to us
if the connection has been dropped, so the early RST doesn't serve the
genuine class of connections much. In summary, we can reduce the number
of packets we send by a factor of two without any loss in functionality
by ensuring that RST packets are not sent when dropping a connection
from the listen queue.
