The driver would hang during attach on RELENG_6 - by "fixing" the issue
by adding debug print statements I've come to the conclusion that too little
time is being allowed to pass between register updates. Increasing the DELAY
interval by a constant interval eliminates this issue on my hardware.

MFC:
As suggested more than once in the lists, drop -M from flags to mfs
for /tmp and /var. This makes the memory discs swap-backed instead
of malloc-backed. A swap-backed memory disc should not be worse
than a malloc-backed one in any scenario because it will start
touching swap only when needed. OTOH, a malloc-backed disc can
starve limited kernel resources and evenually crash the system.
Reflect the change in the rc.conf(5) manpage. Also stop telling
lies there about softupdates: it does not waste disc space, it
just can delay its freeing.

Fix IP_SENDSRCADDR semantics.
* To use this option with a UDP socket, it must be bound to a local port,
and INADDR_ANY, to disallow possible collisions with existing udp inpcbs
bound to the same port on other interfaces at send time.
* If the socket is bound to INADDR_ANY, specifying IP_SENDSRCADDR with
INADDR_ANY will be rejected as it is ambiguous.
* If the socket is bound to an address other than INADDR_ANY, specifying
IP_SENDSRCADDR with INADDR_ANY will be disallowed by in_pcbbind_setup().

Disable RPC exponential back-off for FreeBSD.org systems (IE. hidden
behind _FREEFALL_CONFIG). This is done mainly to make NIS even more
resistant to packet loss.
This is not enabled by default for "normal" FreeBSD since it might cause
the server providing the RPC service to be hit heavily with RPC traffic
in case of problems. freefall.FreeBSD.org and hub.FreeBSD.org have been
running with a patch similar to this for a couple of weeks.

MFC 1.50:
- Bump _yplib_timeout limit from 10 to 20 seconds to better handle
packet loss when talking to a NIS server.
- Set 1 second retry timeout to further realistically handle UDP
packet loss for yp_next packet bursts. If the packet hasn't come
back within 1 second its rather unlikely to come back at all. There
is still back-off mechanism in RPC so if there is another reason
than packet loss for the lack of response within 1 second, the NIS
server will not be totally bombarded with requests.
This reduces the risk of NIS failing with:
yp_next: clnt_call: RPC: Timed out
considerably. This is mainly a problem if you have larger NIS maps
(like at FreeBSD.org) since enumerations of the lists will cause a UDP
packet bursts where a few packets being lost once in a while do
happen.

Fix undirected broadcast sends for the case where SO_DONTROUTE has also

IP_ONESBCAST is actually a special case of SO_DONTROUTE, as 255.255.255.255

If IP_ONESBCAST has been set at the socket layer, also perform destination
interface lookup for point-to-point interfaces based on the destination
address of the link; previously it was not possible to use the option with
such interfaces; also, the destination/broadcast address fields map to the
same field within struct ifnet, which doesn't help matters.
