Also, add ioctls SIOCGIFADDRPREF/SIOCSIFADDRPREF to get/set preference
numbers for addresses. Make ifconfig(8) set/display preference
numbers.
To activate source-address selection policies in your kernel, add
'options IPSELSRC' to your kernel configuration.
Miscellaneous changes in support of source-address selection:
1 Factor out some common code, producing rt_replace_ifa().
2 Abbreviate a for-loop with TAILQ_FOREACH().
3 Add the predicates on IPv4 addresses IN_LINKLOCAL() and
IN_PRIVATE(), that are true for link-local unicast
(169.254/16) and RFC1918 private addresses, respectively.
Add the predicate IN_ANY_LOCAL() that is true for link-local
unicast and multicast.
4 Add IPv4-specific interface attach/detach routines,
in_domifattach and in_domifdetach, which build #ifdef
IPSELSRC.
See in_getifa(9) for a more thorough description of source-address
selection policy.
if the kernel does not set the interface up after we set an address,
do it explicitly, unless we (previously) set it down on user request.
This will allow the network drivers to be "fixed" while keeping visible
behaviour the same. Part of fixing PR 30694.
to automatically bring up interfaces, then we should move that code into
ifconfig(8) and out of the kernel, not cycle the interface up and down. Fixes
PR 9400 -- ifconfig(8) was not working as documented.
stats after printing them.
(Basically this just calls SIOCZIFDATA instead of SIOCGIFDATA).

However, he suggested using -c, and cgd (reasonably) noted that -z for
"zero" was probably more reasonable.
I've also changed the code very slightly.
* bssid xx:xx:xx:xx:xx:xx -- set the desired BSSID of an 802.11
interface.
* -bssid -- unset the desired BSSID of an 802.11 interface, so
the interface will choose automatically (default).
* channel x -- set the channel (radio frequency) of an 802.11 interface.
Current BSSID and channel are now reported in the 802.11 status
display, if supported by the interface.
Above changes from David Young <dyoung@ojctech.com>, with some slight
changes by me (use ethers(3) functions rather than hand-parsing/printing
the 802.11 address).
Document bssid/-bssid/channel, and clean up markup of parentheticals
in the manual page.
